mtd: spi-nor-core: Add fixups for Cypress s25hl-t/s25hs-t
The nor->ready() and spansion_sr_ready() introduced earlier in this
series are used for multi-die package parts.
The nor->quad_enable() sets the volatile QE bit on each die.
The nor->erase() is hooked if the device is not configured to uniform
sectors, assuming it has 32 x 4KB sectors overlaid on bottom address.
Other configurations, top and split, are not supported at this point.
Will submit additional patches to support it as needed.
The post_bfpt/sfdp() fixes the params wrongly advertised in SFDP.
