mtd: cfi-flash: fix write_buff() for 64 bit systems ...

write_buff() uses ~(flash_info.portwidth - 1) to mask lower bits of addr. This
causes higher 32 bits of addr to be discarded on a 64 bit system, since
flash_info.portwidth is 32 bits long (unsigned int) and addr is 64 bits long
(unsigned long).

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.

cfi_flash: add shift option for some cfi memory chips ...

Many cfi chips support 16 and 8 bit modes. Most important
difference is use of so called "Q15/A-1" pin. In 16bit mode this
pin is used for data IO. In 8bit mode, it is an address input
which add one more least significant bit (LSB). In this case
we should shift all adresses by one:
For example 0xaa << 1 = 0x154
