ps3: FLASH ROM Storage Driver

Add a FLASH ROM Storage Driver for the PS3:
  - Implemented as a misc character device driver
  - Uses a fixed 256 KiB buffer allocated from boot memory as the hypervisor
    requires the writing of aligned 256 KiB blocks

Include support for the PS3 FLASH ROM Storage.
This support is required to access the PS3 FLASH ROM, which
contains the boot loader and some boot options.
In general, all users will say Y or M.
As this driver needs a fixed buffer of 256 KiB of memory, it can
be disabled on the kernel command line using "ps3flash=off", to
not allocate this fixed buffer.
