powerpc/mpc52xx: Fix some pr_debug() issues

Browse source 
Fix some pr_debug() issues in mpc52xx_pci.c:

- use __func__ to print function names
- use "%pr" to print struct resource entries
- use "%pa" to print a resource_size_t (phys_addr_t)

The latter two fix several build warnings:

  ../arch/powerpc/platforms/52xx/mpc52xx_pci.c: In function 'mpc52xx_pci_setup':
  ../include/linux/kern_levels.h:5:18: warning: format '%x' expects argument of type 'unsigned int', but argument 2 has type 'resource_size_t' {aka 'long long unsigned int'} [-Wformat=]

The change to print mem_resource[0] is for consistency within this
source file and to use the kernel API -- there were no warnings here.
