mtd: m25p80: make CONFIG_M25PXX_USE_FAST_READ safe to enable
This patch adds a flag to struct flash_info indicating that
fast_read is not supported. This now gives the following logic
when determing whether to enable fastread:
If the flash chip does not support fast_read, then disable it.
Otherwise:
1) enable fast_read if device node contains m25p,fast-read
2) enable fast_read if forced in Kconfig
This makes enabling CONFIG_M25PXX_USE_FAST_READ a safe option
since we no longer enable the fast_read option unconditionally.
For now fast_read is disabled for the everspin mr25h256 and the
catalyst devices. Others may need the flag aswell.
