In svs_bank_resource_setup() there is a "big" switch assigning different
names depending on sw_id and type and this will surely grow: for example
MT8186 has got a two-line type (high/low) SVS bank for CPU_BIG, and this
would require more switch nesting.
Simplify all of this by changing that to a devm_kasprintf() call that
will concatenate the SW_ID string (e.g. SVSB_CPU_LITTLE) with the Type
string (e.g. _LOW), resulting in the expected full bank name (e.g.
SVSB_CPU_LITTLE_LOW).
This being a dynamic allocation can be slower, but this happens only
once in the life of this driver and it's not a performance path, so it's
totally acceptable.
