[PATCH v2] treewide: Enable SPL_SEPARATE_BSS if SPL_BSS_START_ADDR is used

If .bss does not immediately follow the end of the image, then
CONFIG_SPL_SEPARATE_BSS must be selected. Typically, the location of bss
is specified by using CONFIG_SPL_BSS_START_ADDR in a linker script. On
these arches, CONFIG_SPL_SEPARATE_BSS should be enabled. If there is an
option to use an alternate boot script (e.g. CONFIG_SPL_LDSCRIPT is just
a default), just imply. If there is not, select.

Changes in v2:
- Add "if SPL" to selects to avoid config error
