sparc/of: Move of_device fields into struct pdev_archdata

This patch moves SPARC architecture specific data members out of
struct of_device and into the pdev_archdata structure.  The reason
for this change is to unify the struct of_device definition amongst
all the architectures.  It also remvoes the .sysdata, .slot, .portid
and .clock_freq properties because they aren't actually used by
anything.

A subsequent patch will replace struct of_device entirely with struct
platform_device and the of_platform support code will share common
routines with the platform bus (but the bus instances themselves can
remain separate).

This patch also adds 'struct resources *resource' and num_resources
to match the fields defined in struct platform_device.  After this
change, 'struct platform_device' can be used as a drop-in replacement
for 'struct of_platform'.

This change is in preparation for merging the of_platform_bus_type
with the platform_bus_type.
