The pool is created thru devm_gen_pool_create, so the call to
gen_pool_destroy is not necessary.
Instead the sram-clock must be turned off again if it exists.

Replace a call to deprecated devm_request_and_ioremap by devm_ioremap_resource.
Found with coccicheck and this semantic patch:

This driver requests and remaps a memory region as configured in the
device tree. It serves memory from this region via the genalloc API. It
optionally enables the SRAM clock.
Other drivers can retrieve the genalloc pool from a phandle pointing to
this drivers' device node in the device tree.
The allocation granularity is hard-coded to 32 bytes for now, to make the
SRAM driver useful for the 6502 remoteproc driver. There is overhead for
bigger SRAMs, where only a much coarser allocation granularity is needed:
At 32 bytes minimum allocation size, a 256 KiB SRAM needs a 1 KiB bitmap
to track allocations.
