mtd: spi-nor-core: Add fixups for s25fs512s

This patch adds fixups for s25fs512s to address the following issues
from reading SFDP:

  - Non-uniform sectors by factory default. The setting needs to be
    checked and assign erase hook as needed.
  - Page size is wrongly advertised in SFDP.
  - READ_1_1_2 (3Bh/3Ch), READ_1_1_4 (6Bh/6Ch), and PP_1_1_4 (32h/34h)
    are not supported.
  - Bank Address Register (BAR) is not supported.

In addition, volatile version of Quad Enable is used for safety.

Based on patch by Takahiro Kuwano with s25fs_s_post_bfpt_fixup() updated
to use 4-byte address commands instead of extended address mode and the
page_size is fixed to 256

For future use, manufacturer code should be moved out from framework
code as same as in Linux.
