Simon Glass 21c1bf9628 flash: Only erase flash block that contain data ...

It wastes time to erase blocks that are already erased and it is faster
on stm32 to check first. Add a check in flash_physical_erase() on all
chips, using a common flash_is_erased() function.

BUG=none
BRANCH=snow,link
TEST=manual
Do software sync in U-Boot and see that it succeeds. This tests that
we can still erase and then boot a written image. It typically saves
a second on a full sync over i2c.

SMDK5250 # cros_test swsync -f
SF: Detected W25Q32 with page size 4 KiB, total 4 MiB
Flashing RW EC image: erasing, writing, done
Flashing RO EC image: erasing, writing, done
Full software sync completed in 22.949s
SMDK5250 #

Also see that second erase is faster:

SMDK5250 # time mkbp erase rw

time: 0.952 seconds, 952 ticks
SMDK5250 # time mkbp erase rw

time: 0.054 seconds, 54 ticks
SMDK5250 #
