wifi: ath12k: fix rx_mpdu_start layout for QCC2072

Browse source

QCC2072's rx_mpdu_start TLV has a different field layout from QCN9274.
Reusing struct rx_mpdu_start_qcn9274 in hal_rx_desc_qcc2072 causes the
RX datapath to read the wrong offsets for info2, info4, pn[] and
phy_ppdu_id, producing corrupted sequence number, PN, ppdu_id and
mpdu-info flags (encrypted, fragment, addr2/addr4 valid).

Add a dedicated struct rx_mpdu_start_qcc2072 that matches the actual
hardware descriptor layout, and use it in hal_rx_desc_qcc2072.

Tested-on: QCC2072 hw1.0 PCI WLAN.COL.1.0.c2-00188-QCACOLSWPL_V1_TO_SILICONZ-1
