8f62f59f83 mtd: parsers: qcom: incompatible with spi-nor 4k sectors
Partition size and offset value are in block size units, which is the
same as 'erasesize'. But when 4K sectors are enabled erasesize is set to
4K. Bail out in that case.

c95310e1b3 mtd: parsers: qcom: Fix error condition
qcom_smem_get() does not return NULL, and even if it did, the NULL
condition is usually not an error but a success condition and should
not trigger an error trace.

Let's replace IS_ERR_OR_NULL() by IS_ERR().

This fixes the following smatch warning:
drivers/mtd/parsers/qcomsmempart.c:109 parse_qcomsmem_part() warn: passing zero to 'PTR_ERR'

803eb124e1 mtd: parsers: Add Qcom SMEM parser
NAND based Qualcomm platforms have the partition table populated in the
Shared Memory (SMEM). Hence, add a parser for parsing the partitions
from it.
