Add BHI260 init retry, revert BMM150 firmware (no magnetometer on PCB)

Browse source 
The T-Watch Ultra does not have a BMM150 magnetometer — the BHI260AP
aux I2C pins are tied to VDD1V8 (confirmed from schematic). The
BOSCH_BHI260_AUX_BMM150_GPIO firmware fails to init because there
is no BMM150 to discover.

Reverted to BOSCH_BHI260_GPIO. Added 10s retry interval for BHI260
init failures instead of single-attempt with no recovery.
