Migrate to smsc911x ethernet driver instead of smc911x driver.
The smsc911x ethernet driver supports NAPI and performs better
under heavy traffic. With the smc911x driver we were witnessing
very high iowait time for high IO load over NFS.

Initialize vmmc and vmmc_aux regulators
Note that the omap3evm_twldata.vmmc1 and omap3evm_twldata.vsim
are set in omap3_evm_i2c_init() to avoid a merge conflict
with the MFD tree. These will be initialized in omap3evm_i2c_boardinfo
as a fix later on.

Added runtime programming for the differences in EHCI interface between
OMAP3EVM revisions (Rev >= E) and (Rev < E).
Changes:
- EHCI PHY reset GPIO pin is 21 on Rev >= E while Rev < E
uses GPIO pin 135.
- Rev >= E uses EHCI Vbus enable GPIO22 line.
- Rev >= E uses GPIO61 to select EHCI port either on main board or
on Mistral Daughter Card (MDC). OMAP3EVM Rev < E doesn't have
EHCI port on main board.
- Currently GPIO61 it programmed to enable EHCI port on main
board only.

Added function to differentiate between the OMAP3EVM revisions. The

The mainline merge of the 3430SDP support (commit 6fdc29e2)
seems to have messed up the 3430 defconfig completely.
Update the defconfig using a known good version
(SDP defconfig from v2.6.26-omap2 and current beagle defconfig)
as reference.
The image size is now 1.9 MB down from 2.4 MB earlier, and
the number of modules is 8, down from 203. Build time also
scales proportionally.
Other support (OneNAND, etc) can be enabled as needed.
Note that this patch intentionally does not update CONFIG_FB
related options to avoid merge conflicts with the pending
omap_dss2 patches.

This patch disables a GPIO module when all pins of a GPIO
module are inactive (clock gating forced at module level) and
enables the module when any gpio in the module is requested.
The module is enabled only when "mod_usage" indicates that no GPIO
in that module is currently active and the GPIO being requested
is the 1st one to be active in that module.
Each module would be disabled in omap_gpio_free() API when all
GPIOs in a particular module becomes inactive. The module is
re-enabled in omap_gpio_request() API when a GPIO is requested
from the module that was previously disabled.
Since individual GPIO's bookkeeping is added in this patch
via "mod_usage", the same is used in omap_set_gpio_debounce()
& omap_set_gpio_debounce_time() APIs to ensure that the gpio being
used is actually "requested" prior to being used (Nishant Menon's
<nm@ti.comSuggestion)
GPIO module level details are specific to hardware and hence
introducing this patch in low level layer (plat-omap/gpio.c)

map_iovm_area is only called from a context where its second argument is
known not to be NULL, so drop the unnecessary test. If new could be NULL,
the initialization of da should be moved below the test.
A simplified version of the semantic match that detects this problem is as
follows (http://coccinelle.lip6.fr/):
// <smpl>
@match exists@
expression x, E;
identifier fld;

All of the OMAP3 IVA physical address macros in
plat-omap/include/plat/omap34xx.h are wrong[1]:
OMAP34XX_IVA_INTC_BASE: The IVA interrupt controller does not appear
to be accessible from the L3 interconnect, and in any case is
definitely not at 0x40000000; the latter address appears to be the
internal IVA physical address base for the OMAP2420's interrupt control[2].
OMAP34XX_DSP_BASE: The section of L3 physical address space mapped to
the IVA starts at 0x5c000000, not 0x58000000.
OMAP34XX_DSP_MEM_BASE: It's not clear what this refers to, but it's not
in the L3 IVA address space.
OMAP34XX_DSP_IPI_BASE: The Intrusive Port Interface is a relic from
the OMAP2420 days and no longer applies to OMAP3.
OMAP34XX_DSP_MMU_BASE: The DSP MMU is mapped at 0x5d000000, not 0x5a000000.
Nothing that uses these can possibly be working, so drop them. When
future code needs these, correct versions can be added in.
