Matthias Breithaupt e29dc39377 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}"]`.

Matthias Breithaupt 41b346d141 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.

Andrew Dennison f99658200e 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

Andrew Dennison 13811aeacb test_i2c: update to use improved _MockTristate 
* test now checks the actual i2c bus state, not the I2CMaster output
* refactor to eliminate some copy/paste
* tests now work again with this change: 'only change SDA when SCL is stable'
