Some UniPhier boards are equipped with an expansion slot that
some optional SRAM/NOR-flash cards can be attached to. So, run-time
detection of the number of flash banks would be more user-friendly.
Until this commit, UniPhier boards have achieved this by (ab)using
board_flash_wp_on() because the boot failed if flash_size got zero.
Fortunately, this problem was solved by commit 70879a9256 (flash:
do not fail even if flash_size is zero).
Now it is possible to throw away such a tricky workaround. This
commit also enables CONFIG_SYS_MAX_FLASH_BANKS_DETECT for further
refactoring.

This commit merges
arch/arm/cpu/armv7/uniphier/ph1-*/board_postclk_init.c
to
arch/arm/cpu/armv7/uniphier/board_postclk_init.c
Because PH1-Pro4 does not have the BCU block, add __weak to
bcu_init().

Add CONFIG_CMD_PINMON to UniPhier-specific Kconfig and make the
"pinmon" command user-configurable. This command can be disabled
via the configuration if users do not need it.
