json2dts_zephyr: omit disable handler

omit disable handler for the sdcard peripherals,
as they still don't have a driver in zephyr and are not in the board dts.
This way the build in zephyr will not fail.

openocd/jtagspi: Allow users to specify additional init commands
...
This change makes it possible to e.g. use flahs chips that would not be correctly detected by OpenOCD.
All that has to be done is to add `init_commands=["jtagspi set 0 \"name\" {size} {pagesize} {read_cmd} 0 {pprg_cmd} {mass_erase_cmd} {sector_size} {sector_erase_cmd}"]`.

bios: mem_read: reduce number of reads on mapped registers (only supports 32-bit aligned addresses)
...
Instead of reading each individual byte, causing multiple 4-byte requests to each address, this
change results in a single read for each address.
