Page table operation would not fault except:
1. the hypervisor it out of memory to allcate a page for page table operation
2. there is a bug with page table operation in hypervisor or devicemodle
While we assue that these would not happened in our platform when release, so
there is no need to check whether there is a fault with page table operation. However,
for debug version, we would panic the hypervisor if we can't meet the conditions really.

MISRA-C requires that there should be no unused parameters in
functions.
In some cases, we will keep the unused parameters.
vmexit handler is one example. It is used as function pointer.
Some of the vmexit handlers use the input parameter 'vcpu', some of
them don't. We still need to keep the unused parameters 'vcpu' for
those handlers don't use 'vcpu'.
This patch removes the unused parameters that is not being used
unconditionally.
v1 -> v2:
* remove the non-implemented API 'vlapic_id_write_handler'

- Clean up some code regarding to % and / operations since bit
operations are faster.
x % 64U ---> x & 0x3fU
x % 32U ---> x & 0x1fU
x % 16U ---> x & 0xfU
x % 8U ---> x & 0x7U
x % 4U ---> x & 0x3U
x % 2U ---> x & 0x1U
x / 64U ---> x >> 6U
x / 32U ---> x >> 5U
x / 16U ---> x >> 4U
x / 8U ---> x >> 3U
x / 4U ---> x >> 2U
x / 2U ---> x >> 1U

V4:
- Moved error checking to vdev_hostbridge_cfgwrite/vdev_hostbridge_cfgread
V3:
- Unified ops calling and implemented deinit/cfgwrite/cfgread ops,
previously only init op is implemented

V4:
- Renamed members for struct pcibar and changed code accordingly
V3:
- Do not use ASSERT
- Use EPT_XX defines when claling ept_mr_add
- Report 64-bit MMIO physical bar to UOS as 32-bit virtual bar
(assume bar size is always less than 4GB), which removed quite some of
64-bit bar handling code
