lib: utils: Fix reserved memory node for firmware memory

Browse Source 
The commit 9e0ba090 introduced more fine grained permissions for memory
regions and did not update the fdt_reserved_memory_fixup() function. As
a result, the fdt_reserved_memory_fixup continued to use the older coarse
permissions which causes the reserved memory node to be not inserted
into the DT.

To fix the above issue, we correct the flags used for memory region
permission checks in the fdt_reserved_memory_fixup() function.

Fixes: 9e0ba090 ("include: sbi: Fine grain the permissions for M and SU modes")
