wifi: mt76: mt7925: use irq_map for chip-specific interrupt handling

The mac_reset and resume paths use the hardcoded MT_INT_RX_DONE_ALL
constant (bits 0-2) to re-enable RX interrupts. This is correct for
MT7925 (RX rings 0, 1, 2) but wrong for chips using different ring
indices.

Define a per-chip irq_map with the correct RX interrupt enable bits and
replace hardcoded MT_INT_RX_DONE_ALL with irq_map field reads in the
resume and mac_reset paths. Add the MT7927 irq_map with interrupt bits
matching its RX ring layout (rings 4, 6, 7), selected at probe time
based on PCI device ID.

This ensures the correct interrupt bits are enabled regardless of the
chip variant.
