The CONFIG_BLK conversion involves quite invasive changes in the U-Boot

bch: don't use __BSD_VISIBLE to test for fls
Commit 4ecc988301bc8e981e6d7538c57cdb3aa82f7c1d assumes fls is in libc

Switch the test for __BSD_VISIBLE to one for __DragonFly__ and
__FreeBSD__ to unbreak the build on OpenBSD.
This commit removes definitions of CONFIG_SYS_BARGSIZE defined to be
equal to CONFIG_SYS_CBSIZE in numerous configuration files.
We remove such definitions in two situations:
- CONFIG_SYS_CBSIZE is otherwise not defined in the board
configuration file, which means the default value of
CONFIG_SYS_CBSIZE == 256 applies. In this case, the default value
of CONFIG_SYS_BARGSIZE == 512 (common/image.c) is suitable, as it is

to a value equal or less than 512. In this case, the default value
