Subject: [PATCH v2 1/6] soc: qcom: ocmem: Fix NUM_PORTS & NUM_MACROS macros

Since we're using these two macros to read a value from a register, we
need to use the FIELD_GET instead of the FIELD_PREP macro, otherwise
we're getting wrong values.

So instead of:

  [    3.111779] ocmem fdd00000.sram: 2 ports, 1 regions, 512 macros, not interleaved

we now get the correct value of:

  [    3.129672] ocmem fdd00000.sram: 2 ports, 1 regions, 2 macros, not interleaved

Fixes: 88c1e9404f1d ("soc: qcom: add OCMEM driver")
