[U-Boot] [PATCH v2 5/5] remoteproc: k3_rproc: Rename to ti_k3_arm64_rproc

k3_rproc driver is specifically meant for controlling an arm64
core using TISCI protocol. So rename the driver, Kconfig symbol,
compatible and functions accordingly.
While at it drop this remoteproc selection for a53 defconfig.
