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.

soc/cores/i2c: rewrite state machine

* Fix READ: was reading too many bits
* CLeaner transitions between states: ACK=>IDLE with scl=0. Other to IDLE with scl=1
* Now cleanly supports RESTART
* conceptual support for compound commands - not exposed yet
* fix tests: now appears to be I2C compliant
