flash/nor: Add erased_value to drivers and pass it to targets
struct flash_driver has a default_padded_value field that is similar,
but it can be changed by the user for the specific purpose of padding.
Add a new erased_value field and initialize it for all targets,
particularly stm32lx, xmc4xxx and virtual.
Use this value in core.c:default_flash_mem_blank_check(), the slow path.
Extend the target API to pass erased_value down to target code.
Adding an argument ensures that we catch all callers.
This allows us to merge xmc4xxx.c:xmc4xxx_blank_check_memory() into
armv7m:armv7m_blank_check_memory().
It further allows us to use default_flash_blank_check() in place of
xmc4xxx.c:xmc4xxx_flash_blank_check(), adding a potential slow path
fallback, as well as stm32lx:stm32lx_erase_check(), adding the potential
armv7m fast path with fallback to default_flash_mem_blank_check().
Fix a mips32 code comment while at it (zeroed -> erased).
The armv4_5 and mips32 target implementations will now error out if an
erase value other than 0xff is used, causing default_flash_blank_check()
to fall back to the default_flank_mem_blank_check() slow path.
