hv: fix integer violations

Browse Source 
- Fix the integer violations related to the following rules:
  1. The operands to shift operations (<<, >>) shall be unsigned
     integers.
  2. The operands to bit operations (&, |, ~) shall be unsigned
     integers.

- Replace 12U with CPU_PAGE_SHIFT when it is address shift case.

v1 -> v2:
 * use existed MACRO to get bus/slot/func values
 * update PCI_SLOT MACRO to make it more straightforward
 * remove the incorrect replacement of 12U with CPU_PAGE_SHIFT
