s28hx_t_post_bfpt_fixup() fixes erase opcode, erase size, and page size.
s25_post_bfpt_fixup() is doing same thing including multi-die support.
We can consolidate s28hx_t_post_bfpt_fixup() and s25_post_bfpt_fixup()
into one named s25_s28_post_bfpt_fixup().
In s25_s28_post_bfpt_fixup(), set_4byte() is called to force the device to
be 4-byte addressing mode. In S28HS02GT datasheet, the B7 opcode is missing
but it works actually (confirmed).
