Subject: [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.
