A subsequent commit to cleanup powerpc's asm/prom.h leads to build
errors in mpc85xx_edac.c due to missing headers. Include all required
headers directly to avoid the build failure.

The commit
cb51a371d0 ("EDAC/ghes: Setup DIMM label from DMI and use it in error reports")
enforced that both the bank and device strings passed to
dimm_setup_label() are not NULL.
However, there are BIOSes, for example on a
HPE ProLiant DL360 Gen10/ProLiant DL360 Gen10, BIOS U32 03/15/2019
which don't populate both strings:
Handle 0x0020, DMI type 17, 84 bytes
Memory Device
Array Handle: 0x0013
Error Information Handle: Not Provided
Total Width: 72 bits
Data Width: 64 bits
Size: 32 GB
Form Factor: DIMM
Set: None
Locator: PROC 1 DIMM 1 <===== device
Bank Locator: Not Specified <===== bank
This results in a buffer overflow because ghes_edac_register() calls
strlen() on an uninitialized label, which had non-zero values left over
from krealloc_array():
detected buffer overflow in __fortify_strlen

The label contains garbage because the commit in Fixes reallocs the
DIMMs array while scanning the system but doesn't clear the newly
allocated memory.
Change dimm_setup_label() to always initialize the label to fix the
issue. Set it to the empty string in case BIOS does not provide both
bank and device so that ghes_edac_register() can keep the default label
given by edac_mc_alloc_dimms().

Pull EDAC updates from Borislav Petkov:
- Switch ghes_edac to use the CPER error reporting routines and
simplify the code considerably this way
- Rip out the silly edac_align_ptr() contraption which was computing
the size of the private structures of each driver and thus allowing
for a one-shot memory allocation. This was clearly unnecessary and
confusing so switch to simple and boring kmalloc* calls.
- Last but not least, the usual garden variety of fixes, cleanups and
improvements all over EDAC land

The dmc520 driver requires that at least one interrupt line, out of the
ten possible, is configured. The driver prints an error and returns
-EINVAL from its .probe function if there are no interrupt lines
configured.
Don't print a KERN_ERR level message for each interrupt line that's
unconfigured as that can confuse users into thinking that there is an
error condition.
Before this change, the following KERN_ERR level messages would be
reported if only dram_ecc_errc and dram_ecc_errd were configured in the
device tree:
dmc520 68000000.dmc: IRQ ram_ecc_errc not found
dmc520 68000000.dmc: IRQ ram_ecc_errd not found
dmc520 68000000.dmc: IRQ failed_access not found
