Mirrors `HAL_PMU_LoadCalData()` from SDK drivers/hal/bf0_hal_pmu.c. Without it, BUCK / LPSYS_LDO / VRET / PERI_LDO / AON_BG run on chip-default voltages, leaving the RF supplies slightly off-spec — HCI commands succeed but no advertising packets reach the air on production parts. Reads from the existing `Bank1Calibration` decoded in `efuse::Bank1Primary` and writes the five PMU registers (with the SDK's non-Letter-vs-Letter split). Returns false when the eFUSE block is blank (hpsys_ldo_vout == 0), matching the SDK guard at bf0_sys_cfg.c:262. Signed-off-by: Haobo Gu <[email protected]>
