[lvc-project] [PATCH] mtd: lpddr_cmds: Added literal suffix

[Denis Arefev]

The value of an arithmetic expression
1 << lpddr->qinfo->DevSizeShift is subject to overflow
due to a failure to cast operands to a larger data
type before performing arithmetic

Found by Linux Verification Center (linuxtesting.org) with SVACE.
