cfi_flash: introduce flash cmdset fixup ...

Move fixing up like geometry reversal into separate functions.

by altering the qry structure directly, which makes the sector init
code slightly cleaner.

cfi_flash: Read whole QRY structure in one go ...

Read out the whole CFI Standard Query structure after successful cfi
identification. This allows subsequent code to access this information
directly without having to go through flash_read_uchar() and friends.

cfi_flash: Introduce read and write accessors ...

Introduce flash_read{8,16,32,64) and flash_write{8,16,32,64} and use
them to access the flash memory. This makes it clearer when the flash
is actually being accessed; merely dereferencing a volatile pointer
looks just like any other kind of access.
