wifi: ath12k: enable ath12k AHB support

Currently only PCI devices are supported in Ath12k driver. Refactor
Ath12k module_init and module_exit to include Ath12k AHB support.

Add Ath12k AHB support in Kconfig with dependency on Remoteproc
driver. Ath12k AHB support relies on remoteproc driver for firmware
download, power up/down etc.
