When building a 32-bit config which has the above MFD item as module
but OLPC_XO1_PM is enabled =y - which is bool, btw - the kernel fails
building with:

ld: arch/x86/platform/olpc/olpc-xo1-pm.o: in function `xo1_pm_remove':
/home/boris/kernel/linux/arch/x86/platform/olpc/olpc-xo1-pm.c:159: undefined reference to `mfd_cell_disable'
ld: arch/x86/platform/olpc/olpc-xo1-pm.o: in function `xo1_pm_probe':
/home/boris/kernel/linux/arch/x86/platform/olpc/olpc-xo1-pm.c:133: undefined reference to `mfd_cell_enable'
make: *** [Makefile:1030: vmlinux] Error 1

Force MFD_CS5535 to y if OLPC_XO1_PM is enabled.
