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.
