Subject: [PATCH 1/2] MIPS: octeon: Fix cvmx_writeq_csr/cvmx_readq_csr on 32-bit builds

Test 32-bit builds have an error in cvmx_writeq_csr/cvmx_readq_csr:

arch/mips/include/asm/octeon/cvmx.h:282:24: error: cast from pointer to integer of different size [-Werror=pointer-to-int-cast]

As the default for allyesconfig/allmodconfig is 32-bit, fixing these
functions for 32-bit is needed to enable Cavium Octeon drivers for
COMPILE_TEST.
