x86/earlyprintk: Put CONFIG_PCI-only functions under the #ifdef

Two static functions are only used if CONFIG_PCI is defined, so only
build them if this is the case. Fixes the build warnings:

  arch/x86/kernel/early_printk.c:98:13: warning: ‘mem32_serial_out’ defined but not used [-Wunused-function]
   static void mem32_serial_out(unsigned long addr, int offset, int value)
             ^
  arch/x86/kernel/early_printk.c:105:21: warning: ‘mem32_serial_in’ defined but not used [-Wunused-function]
   static unsigned int mem32_serial_in(unsigned long addr, int offset)
                     ^

Also convert a few related instances of uintXX_t to kernel specific uXX
defines.
