Now that the console system itself will clearly differentiate loglevels,
it is no longer necessary to explicitly add "ERROR: " in front of every
BIOS_ERR message to help it stand out more (and allow automated tooling
to grep for it). Removing all these extra .rodata characters should save
us a nice little amount of binary size.
This patch was created by running
find src/ -type f -exec perl -0777 -pi -e 's/printk\(\s*BIOS_ERR,\s*"ERROR: /printk\(BIOS_ERR, "/gi' '{}' ';'
and doing some cursory review/cleanup on the result. Then doing the same
thing for BIOS_WARN with
's/printk\(\s*BIOS_WARNING,\s*"WARN(ING)?: /printk\(BIOS_WARNING, "/gi'

The I2C pad control registers of Picasso and Cezanne are identical and
the one of Sabrina is a superset of it, so factor out the functionality.
To avoid having devicetree settings that contain raw register bits, the
i2c_pad_control struct is introduced and used. The old Picasso code for
this had the RX level hard-coded for 3.3V I2C interfaces, so keep it
this way in this patch but add a TODO for future improvements.

No mainboard in the current tree implements mainboard_i2c_override. In a
follow-up commit the i2c_pad_control struct is introduced to be able to
make more parameters controllable by devicetree settings in the future.

Some of the I2C buses are required to operate at different voltage level
compared to other I2C buses eg. I2C bus to Google Security Chip (GSC)
should be at 1.8V level. By default, all the I2C buses are initialized
to operate at 3.3 V. Add support to configure I2C pad RX select through
devicetree and update the concerned devicetree.

if ENV_X86 is not true we had several compile errors in i2c code. Fix
them before we add code for psp_verstage which is non-x86.
