ASoC: aw88399: skip BSTS check when boost converter is bypassed
The sysst check in aw_dev_check_sysst() requires BSTS (boost finished)
to assert, but on hardware where the boost converter is bypassed via
external power supply (BSTCTRL10 register 0x69, EN_HVBAT bit 2 set),
BSTS (SYSST register 0x01, bit 9) will never assert.
The vendor's generic driver (aw883xx) handles this by reading EN_HVBAT and
conditionally masking out BSTS from the sysst check. The in-tree driver
missed this logic when the original code was ported upstream.
Add the same conditional check, matching the vendor driver's
aw_dev_sysst_check() implementation.
