device/dram: Add addtional LPDDR4 speed grades

Add additonal LPDDR4 speed grades. This is needed because the limited
set has casued confusion when the reported speed did not match
expectations. There does not seem to be a definitive list of LPDDR4
speed grades, so this list is derieved from JEDEC 209-4C and a survey
of commonly used LPDDR4 speed grades.

BUG=b:194184950
TEST=Boot, dmidecode -t 17 reports correct speed
BRANCH=None
