mtd: spi-nor: spansion: switch cypress_nor_get_page_size() to use vreg_offset

All users of cypress_nor_get_page_size() but S25FS256T retrieve n_dice
and vreg_offset from SFDP. S25FS256T does not define the SCCR map to
retrive the vreg_offset, but it does support it: SPINOR_REG_CYPRESS_VREG.
Switch cypress_nor_get_page_size() to always use vreg_offset so that we
use the same code base for both single and multi chip package flashes.
cypress_nor_get_page_size() is now called in the post_sfdp() hook instead
of post_bfpt(), as vreg_offset and n_dice are parsed after BFPT.
Consequently the null checks on n_dice and vreg_offset are moved to
the post_sfdp() hook.
