soc/intel/broadwell_de: Re-read SPD on CRC error

I2C bus does not guarantee data integrity. As result, sometimes
we end up detecting CRC errors and not adding DIMMs to SMBIOS tables.
This change adds re-tries on such errors.

TEST=let OCP monolake run without fan and try reading SPD data in tight
loop. CRC errors were reported but subsequent retries were error free.
