[riscv] Add a .pf32 build target for padded parallel flash images

Browse Source 
QEMU's -pflash option requires an image that has been padded to the
exact expected size (32MB for all of the supported RISC-V virtual
machines).

Add a .pf32 build target which is simply the equivalent .sbi target
padded to 32MB in size, to simplify testing.
