[PATCH] rockchip: Pinebook Pro: Do not initialize i2c before relocation

The i2c locks up when initialized before relocation, and it stays broken in Linux as well breaking the ability to boot Linux.
The i2c bus and pmic was not actually used in pre-reloc before commit ad607512f575 ("power: pmic: rk8xx: Support sysreset shutdown method")
The cause is not known.
This is board-specific, other boards that do not add the option to include the i2c bus in pre-reloc DT are not affected.

Thanks for checking this out, I had noticed a regression and had got as far as bisecting it but not getting to a fix.
Tom: can we get this pulled into 2023.01 please?

Probably should be, yes. Kever, are there any other rockchip must-fixes for v2023.01? I can take this directly if you don't have others and/or don't want to make up a PR, thanks!
