Remove some unnecessary blank lines to accord with Kernel's coding style.
Also remove vcpu_get_itir_on_fault due to no reference to it.

1. Increase the size of data area to 64M
2. Support more vcpus and memory, 128 vcpus and 256G memory are supported
for guests.
3. Add the boundary check for memory and vcpu allocation.
With this patch, kvm guest's data area looks as follow:
*
* +----------------------+ ------- KVM_VM_DATA_SIZE
* | vcpu[n]'s data | | ___________________KVM_STK_OFFSET
* | | | / |
* | .......... | | /vcpu's struct&stack |
* | .......... | | /---------------------|---- 0
* | vcpu[5]'s data | | / vpd |
* | vcpu[4]'s data | |/-----------------------|
* | vcpu[3]'s data | / vtlb |
* | vcpu[2]'s data | /|------------------------|
* | vcpu[1]'s data |/ | vhpt |
* | vcpu[0]'s data |____________________________|
* +----------------------+ |
* | memory dirty log | |
* +----------------------+ |
* | vm's data struct | |
* +----------------------+ |
* | | |
* | | |
* | | |
* | | |
* | | |
* | | |
* | | |
* | vm's p2m table | |
* | | |
* | | |
* | | | |
* vm's data->| | | |
* +----------------------+ ------- 0
* To support large memory, needs to increase the size of p2m.
* To support more vcpus, needs to ensure it has enough space to
* hold vcpus' data.

Using vt-d, kvm guests can be assigned physcial devices, so
this patch introduce a new mmio type (directed mmio)
to handle its mmio access.
