board: ti: common: board_detect: Fix EEPROM offset read for 1-byte 

EEPROM detection logic in ti_i2c_eeprom_get() involves reading the total
size followed by reading 1-byte size with an offset 1. This commit fixes
the header matching issue in commit 9f393a2d7a ("board: ti: common:
board_detect: Fix EEPROM read quirk for 2-byte").

In the previous commit, the value with one offset is being read into
offset_test, but the pointer used to match was still ep. After reading
with an offset 1, the second byte of the header is compared with the 1-byte
data read from EEPROM. This is taken care by comparing proper first byte
value from the header.
