[PATCH v2 6/8] ath11k: add hw_ops for pdev id to hw_mac mapping

[Anilkumar Kolli <akolli@codeaurora.org>]

pdev_id to hw_mac is different for ipq8074 and ipq6018
Below table has the mapping

pdev_id	ipq8074	ipq6018
-------	------- -------
  0		0	0
  1		2	1
  2		1	Not applicable

Also this patch has moved ath11k_core_init() before
ath11k_ahb_config_irq(), to init .max_radios in hw_params
and Configure external interrupts for available pdev_ids.
