If on your board is more than one flash, you must know
the size of every single flash, for example, for updating
the DTS before booting Linux. So make this function
flash_get_info() extern, and you can have all info
about your flashes.

Commit cfa460adfdefcc30d104e1a9ee44994ee349bb7b removed support
for disabling the "No NAND device found!!!" warning when
CONFIG_SYS_NAND_QUIET_TEST was defined.  This re-adds support
for silencing the warning.

Patch "flash/cfi_flash: Use virtual sector start address, not phys"
introduced a small typo and compilation warning for systems with CFI
legacy support (e.g. hcu4). This patch fixes it.
