Enabling Octal DTR mode in multi-die package parts requires reister setup
for each die. That can be done by simple for-loop. write_enable() takes
effect to all die at once so we can call it before the loop. Besides we
can replace spi_mem_exec_op() calls with spansion_read/write_any_reg().
And finally, we must mask CFR2V[7:4] when changing dummy cycles, as
CFR2V[7] indicates current addressing mode and that should be 1 (4-byte
address mode) for multi-die package parts.

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()

but it works actually (confirmed).

s28hx_t_setup() only checks sector layout setting. To support multi-die
package parts like S28HS02GT, it needs to check device size and assign
ready() hook for multi-die package parts. These are covered in s25_setup()
so we can consolidate s28hx_t_setup() and s25_setup() into one named
s25_s28_setup().

Force the mtd name of spi-nor to "nor" + the driver sequence number:

When CFI MTD NOR device are supported, the spi-nor index is chosen after
the last CFI device defined by CONFIG_SYS_MAX_FLASH_BANKS.
When CONFIG_SYS_MAX_FLASH_BANKS_DETECT is activated, this config
is replaced by to cfi_flash_num_flash_banks in the include file
mtd/cfi_flash.h.
