need the inappropriate kfree to free it in driver's remove function.

Since 39b2bbe3d7 (gpio: add flags argument to gpiod_get*()
functions) which appeared in v3.17-rc1, the gpiod_get* functions
take an additional parameter that allows to specify direction and
initial value for output.
Use this to simplify the driver. Furthermore this is one caller less
that stops us making the flags argument to gpiod_get*() mandatory.
While touching this also do some minor coding style fixes.

The current versions of the trf7970a has an erratum where it returns
an extra byte in the response to 'Read Multiple Block' (RMB) commands.
This command is issued to Type 5 tags (i.e., ISO/IEC 15693 tags) by
the neard daemon.
To handle this, define a new Device Tree property,
't5t-rmb-extra-byte-quirk', which indicates that the associated
trf7970a device has this erratum. The trf7970a device driver
will then ensure that the response length to RMB commands is
reduced by one byte (for devices with the erratum).

When GPIO is not enabled we hit this kind of warning:

net/phy: micrel: Center FLP timing at 16ms
In v2, we add an additional cleanup commit to make an array of strings
static const and to improve const correctness generally. We also no longer
unnecessarily initialize the result variable in
ksz9031_center_flp_timing().
In v3, we remove the unnecessary result variable from ksz9031_config_init()
introduced by a previous version of "net/phy: micrel: Center FLP timing at
16ms".
In v4, we modify the commit message of "net/phy: micrel: Center FLP timing
at 16ms" to replace the awkward quotation of the data sheet's programming
procedure with an explanation of why we program the FLP burst registers and
restart auto-negotiation where we do (config_init).

Link failures have been observed when using the KSZ9031 with HP 1810-8G
and HP 1910-8G network switches. Center the FLP timing at 16ms to help
avoid intermittent link failures.
>From the KSZ9031RNX and KSZ9031MNX data sheets revision 2.2, section
"Auto-Negotiation Timing":
The KSZ9031[RNX or MNX] Fast Link Pulse (FLP) burst-to-burst
transmit timing for Auto-Negotiation defaults to 8ms. IEEE 802.3
Standard specifies this timing to be 16ms +/-8ms. Some PHY link
partners need to receive the FLP with 16ms centered timing;
otherwise, there can be intermittent link failures and long
link-up times.
The PHY data sheet recommends configuring the FLP burst registers after
power-up/reset and immediately thereafter restarting auto-negotiation, so
we center the FLP timing at 16ms and then restart auto-negotiation in the
config_init for KSZ9031.

As Alexander Duyck pointed out that:
struct tnode {
...
struct key_vector kv[1];
}
The kv[1] member of struct tnode is an arry that refernced by
a null pointer will not crash the system, like this:
struct tnode *p = NULL;
struct key_vector *kv = p->kv;
As such p->kv doesn't actually dereference anything, it is simply a
means for getting the offset to the array from the pointer p.
This patch make the code more regular to avoid making people feel
odd when they look at the code.

In big endian cases, macro cpu_to_le16 unfolds to __swab16 which
provides special case for constants. In little endian cases,
__constant_cpu_to_le16 and cpu_to_le16 expand directly to the
same expression. So, replace __constant_cpu_to_le16 with
cpu_to_le16 with the goal of getting rid of the definition of
__constant_cpu_to_le16 completely.
The semantic patch that performs this transformation is as follows:
@@expression x;@@
- __constant_cpu_to_le16(x)
+ cpu_to_le16(x)

The current driver adjust freq formula is:
fe * diff = ppb * pc
Note:
fe: ENET ref clock frequency in Hz
diff = inc_corr - inc: difference between default increment and correction increment
ppb: parts per billion adjustment from base
pc: correction period (in number of fe clock cycles)
The correction increment will be used after N cycles of regular increments,
not every N cycles (with N being the correction period). For example, set ENET_ATCOR=4,
INC=8, INC_CORR=9, there will be 4 increments of 8 (ENET_ATINC[INC]) , followed by 1
increment of 9 (ENET_ATINC[INC_CORR]).
So, the correct formula is:
fe * diff = ppb * (pc + 1)
For ENET_ATCOR, a value 0 disables the correction counter and no corrections occur.
So base on the origin formula, set pc = pc > 1 ? pc - 1 : pc.
