David Karoly 745a40d78a kernel/arm: implement memory attributes 
Set AP[2:0] and XN flags based on page attributes.
PXN is not implemented as it seems to be available only
in L1 descriptors on ARMv7.

Set TEX, B, C flags based on memoryType:
* B_MTR_UC is mapped to Strongly Ordered (TEX=0, B=0, C=0)
* B_MTR_WC is mapped to Shareable Device Memory (TEX=0, B=1, C=0)
* B_MTR_WT is mapped to Outer and Inner Write-Through, no Write-Allocate (TEX=0, B=0, C=1)
* B_MTR_WB is mapped to Outer and Inner Write-Back, no Write-Allocate (TEx=0, B=1, C=1)
* B_MTR_WP has no direct equivalent on the ARM so it's mapped as B_MTR_WB
* default is Write-Back

Implement ARMPagingMethod32Bit::AttributesToPageTableEntryFlags()
for mapping from page attributes to AP[2:0] and XN flags.

Implement ARMPagingMethod32Bit::PageTableEntryFlagsToAttributes()
for the reverse mapping used in Query() and QueryInterrupt()
i.e. recover page attributes from AP[2:0] and XN flags.

Implement ARMPagingMethod32Bit::MemoryTypeToPageTableEntryFlags()
fr mapping from memoryType to TEX, B, C flags.

Implement ARMVMTranslationMap32Bit::Protect() which used to be commented out.

Accessed and modified flags are not implemented yet, so no such
flags are returned from Query() and QueryInterrupt().

Also because of this, we just invalidate TLB on any call to Protect()
without checking whether the page has been accessed.
