Add PHY support for nRF54L15, nRF54L10, and nRF54L05 (PCA10156 DK tested).
The nRF54L uses a fundamentally different peripheral architecture from
nRF52/53:
- DPPI cross-domain routing via PPIB bridges instead of PPI
- Scatter/gather DMA job lists for CCM, AAR, and ECB instead of flat
memory pointers (INPTR/OUTPTR)
- TIMER10 as the PHY timer instead of RTC0
- CCM KEY and NONCE registers use reversed byte order
This change adds:
- nrf54l/phy.c: CCM SG-DMA encrypt/decrypt (FastDecryption mode),
AAR SG-DMA address resolution, PPIB routing init, DPPI channel layout
- nrf54l/phy_hw.h: peripheral aliases, inline hardware functions,
CCM/AAR/ECB attribute constants
- nrf54l/phy_ppi.h: DPPI channel definitions and subscribe/publish helpers
- nrf52/phy_hw.h: extracted nRF52 inline hardware functions (pure
lift-and-shift from ble_phy.c; no logic change)
- src/phy_hw.h, src/phy_ppi.h: MCU dispatcher headers (route to
nrf54l/, nrf53/, or nrf52/ based on MYNEWT_VAL_CHOICE(MCU_TARGET))
- ble_phy.c: four nRF54L conditional blocks; nRF52/53 behavior unchanged
- ble_hw.c: ECB SG-DMA path guarded by NRF_ECB_HAS_ECBDATAPTR
- pkg.yml: nRF54L MCU_TARGET conditions for source_files and include_dirs
- .github/targets/nordic_pca10156_{blehci,btshell}/: CI targets
BLE features enabled: 2M PHY, Coded PHY, LE encryption, LL privacy,
extended advertising, periodic advertising, DLE, DTM.
nRF52/53 behaviour is unchanged.
