Rename i2c_xfer to i2c_xfer_unlocked. Audit all users of i2c_xfer to
see if they can use simple locking semantics or require their own
locking. Since locked accesses are only safe for I2C_XFER_SINGLE
transactions, remove the flags parameter from i2c_xfer. This also makes
the audit a bit easier.
Some remaining applications hold the bus locked across several
transactions that would otherwise be atomic, and a few others implement
complex I2C transactions in multiple commands.
Add a (nondeterministic) verification on the I2C port locking
correctness. This will catch all statically incorrect locking patterns,
although dynamically incorrect locking patterns may not be caught.
Related: Revise the i2c_port_active_count to be a bitmap of the active
ports instead of a count of the active ports. The EC's mutex does not
provide an is_locked() primitive, and we would prefer not to have one.

Fix max brightness for Ryu. The max brightness must be less than
0x80 because the top bit in the lightbar current registers is
reserved. Writing the top bit seems to have undefined behavior.
This fixes the hiccups in the tap for battery sequence which was
ramping brightness to above 0x80 and producing weird results.

Our code base contains a lot of debug messages in this pattern:
CPRINTF("[%T xxx]\n") or ccprintf("[%T xxx]\n")
The strings are taking up spaces in the EC binaries, so let's refactor
this by adding cprints() and ccprints().
cprints() is just like cprintf(), except that it adds the brackets
and the timestamp. ccprints() is equivalent to cprints(CC_CONSOLE, ...)
This saves us hundreds of bytes in EC binaries.
