> This driver is the only SMCCC dependency in iMX8M U-Boot port. Rework
> the driver based on Linux GPCv2 driver to directly control the GPCv2
> block instead of using SMCCC calls. This way, U-Boot can operate the
> i.MX8M power domains without depending on anything else.
> This is losely based on Linux GPCv2 driver. The GPU, VPU, MIPI power
> domains are not supported to save space, since they are not useful in
> the bootloader. The only domains kept are ones for HSIO, PCIe, USB.
