mtd: sh_flctl: Add power management with QoS request
Adds power management code with fine granularity. Every flash control
command is enclosed by runtime_put()/get()s. To make sure that no
overhead is generated by too frequent power state switches, a quality of
service request is issued.

mtd: sh_flctl: Use cached register value for FLCMNCR
Instead of reading out the register, use a cached value. This will
make way for a proper runtime power management implementation.

mtd: sh_flctl: Expand FLCMNCR register bit field
Add support for a new hardware generation. The meaning of some bits
of the FLCMNCR register changed, so some new defines are added
parallel to the existing ones to keep backward compatibility.
The defines allow to choose an appropriate clocking scheme.

mtd/nand/sh_flctl: Move function mtd_to_flctl to fix build failure
This patch fixes a build failure[1] by simply moving the function mtd_to_flctl
beneath the definition of sh_flctl which it uses.

mtd/nand/sh_flctl: Replace the dangerous mtd_to_flctl macro
The original macro worked only when applied to variables named 'mtd'.
While this could have been fixed by simply renaming the macro argument,
a more type-safe replacement is preferred.

mtd: trivial sh_flctl changes
This patch contains a few changes for the sh_flctl driver:
- not sh7723-only driver - get rid of kconfig dependency
- use dev_err() instead of printk()
- use __devinit and __devexit for probe()/remove()
- fix probe() return values
