driver: replace dev_request_mem_region with dev_request_mem_resource ...

dev_request_mem_region doesn't work properly one some SoCs on which
PTR_ERR() values clash with valid return values from dev_request_mem_region.
Replace them with dev_request_mem_resource where possible.

mtd: nand: default bitflip-reporting threshold to 75% of correction strength ...

Based on Kernel commit 240181fd0ffa6 from Brian Norris:

The MTD API reports -EUCLEAN only if the maximum number of bitflips
found in any ECC block exceeds a certain threshold. This is done to
avoid excessive -EUCLEAN reports to MTD users, which may induce
additional scrubbing of data, even when the ECC algorithm in use is
perfectly capable of handling the bitflips.

This threshold can be controlled by user-space (via sysfs), to allow
users to determine what they are willing to tolerate in their
application. But it still helps to have sane defaults.

In recent discussion [1], it was pointed out that our default threshold
is equal to the correction strength. That means that we won't actually
report any -EUCLEAN (i.e., "bitflips were corrected") errors until there
are almost too many to handle. It was determined that 3/4 of the
correction strength is probably a better default.

arm/cpu/lowlevel: fix: possible processor mode change ...

This is a re-application of fix 17644b55.
arm_cpu_lowlevel_init() will set the processor mode to 0x13 (supervisor).
When this function is entered via a different processor mode, register
banking will happen to lr (r14), resulting in an invalid return address.
This fix will preserve the return address manually.
