Revert "mtd: atmel_nand: Support variable RB_EDGE interrupts"

This reverts commit 5ddc7bd43c ("mtd: atmel_nand: Support variable
RB_EDGE interrupts")

Because for current SoCs, the RB_EDGE3(i.e. bit 27) of HSMC_SR
register does not exist, the RB_EDGE0 (i.e. bit 24) is the ready/busy
line edge status bit. It is a datasheet bug.
