misc: eeprom_93xx46: Add quirk to support Microchip 93LC46B eeprom
[ Upstream commit f6f1f8e6e3eea25f539105d48166e91f0ab46dd1 ]
A dummy zero bit is sent preceding the data during a read transfer by the
Microchip 93LC46B eeprom (section 2.7 of[1]). This results in right shift
of data during a read. In order to ignore this bit a quirk can be added to
send an extra zero bit after the read address.
Add a quirk to ignore the zero bit sent before data by adding a zero bit
after the read address.
