dmesg flooded w/ errors (mostly i2c)

I haven't seen this posted else where, but I've noticed a TON of errors in dmesg while trouble shooting other issues.

The biggest error I found and continues from boot onward is the following

i2c i2c-0: mv64xxx: I2C bus locked, block: 1, time_left: 0

some other errors in dmesg Ive noticed AT BOOT

sun50i-h616-pinctrl 300b000.pinctrl: pin PH0 already requested by 5000000.serial; cannot claim for soc:pwm3@0300a000
sun50i-h616-pinctrl 300b000.pinctrl: pin-224 (soc:pwm3@0300a000) status -22
sun50i-h616-pinctrl 300b000.pinctrl: could not request pin 224 (PH0) from group PH0  on device 300b000.pinctrl
platform soc:pwm3@0300a000: Error applying setting, reverse things back
platform soc:pwm3@0300a000: pinctrl_select_state(default) failed!

and a few
sunxi-hdmi soc:hdmi-audio@1: snd_soc_register_card failed

Not sure if these are of any relevance but the i2c error makes it extremely hard to troubleshoot other problems when using dmesg

Edit: These persist regardless of settings in BoardEnv.txt and system.cfg

I do get the audio ones. I'm not using HDMI (nor audio) at all, it would be neat to be able to disable it completely. It likely saves a bit of RAM if it can be disabled.
