rockchip: rk3399: Drop unneeded bob and kevin board specific code

The IO-domain driver will configure io_vsel and always-on/boot-on
regulators will be enabled based on the board device tree now that
required nodes and Kconfig options is enabled for SPL.

Remove the bob and kevin board specific code from the common rk3399.c,
the IO-domain and regulator driver provide similar functionality.
