Subject: [PATCH v5 1/5] dt-bindings: nvmem: fixed-cell: increase bits start
 value to 31

If NVMEM uses a data stride bigger than a byte, the starting bit of the
cell might be bigger than a byte (e.g. if the data comes in the second
byte of the 4-byte word). Allow the staring bit to be 8 or greater to
reflect such usecases.
