spl: Only support bl_len when we have to

Aligning addresses and sizes causes overhead which is unnecessary when we
are not loading from block devices. Remove bl_len when it is not needed.

For example, on iot2050 we save 144 bytes with this patch (once the rest of
this series is applied):

add/remove: 0/0 grow/shrink: 0/3 up/down: 0/-144 (-144)
Function                                     old     new   delta
spl_load_simple_fit                          920     904     -16
load_simple_fit                              496     444     -52
spl_spi_load_image                           384     308     -76
Total: Before=87431, After=87287, chg -0.16%

We use panic() instead of BUILD_BUG_ON in spl_set_bl_len because we still
need to be able to compile it for things like mmc_load_image_raw_sector,
even if that function will not be used.
