flash_fp_mcu: use modalias to detect FP spiid
During bringup there was a point where the spiid for the fingerprint
sensor changed between devices (apparently due to broken TPM firmware
since the TPM is usually the first SPI device)). This resulted in
non-obvious failures when running flash_fp_mcu since many other things
were also not working.
