misc: xilinx_sdfec: validate LDPC code register offsets
The LDPC code register helpers check the target MMIO address after
adding code_id * XSDFEC_LDPC_REG_JUMP to the register base. code_id is
supplied through the ioctl path, so the multiplication and addition can
wrap before the bounds check.
Validate the code_id against the register window size before computing
the final address, then write using the checked address.
