Based off the CONFIG_SPU_FS_MODULE code, only attempt to load platform
modules if the nx-842 pseries/powernv drivers are built as modules.
Otherwise, if CONFIG_DEV_NX_COMPRESS=y,
CONFIG_DEV_NX_COMPRESS_PSERIES=y, CONFIG_DEV_NX_POWERNV=y, the following
message is emitted at boot:
nx_compress: no nx842 driver found.
even though the drivers successfully loads.
This is because in the =y case, the module_init() calls get converted to
initcalls and the nx842_init() runs before the platform driver
nx842_pseries_init() or nx842_powernv_init() functions, which are what
normally set the static platform driver.
