drivers/intel/fsp2_0: remove struct resource usage 

There's no need to use a struct resource type for
fsp_find_reserved_memory(). struct resource is mainly associated
with a device and that memory is added to cbmem after memory init.
Other uses ins FSP 2.0 just use struct range_entry. Use that
instead for consistency.
