sb600spi.c: Add Promontory chipset rev 0x71

Sabrina SoC uses SMBUS revision code 0x71 which behaves exactly as the
promontory chip. Hence add 0x71 as promontory.

BUG=b:228238107
TEST=Build and deploy flashrom in Skyrim. Ensure that flashrom is able
to detect the SPI ROM chip, read from it and write to it successfully.
Ran flashrom_tester on Skyrim (Sabrina SoC) successfully and ensured
that all the tests passed.
