[PATCH v5 5/5] Documentation/vmcoreinfo: Add documentation for 'TCR_EL1.T1SZ'

[Bhupesh Sharma]

Add documentation for TCR_EL1.T1SZ variable being added to
vmcoreinfo.

It indicates the size offset of the memory region addressed by TTBR1_EL1
and hence can be used for determining the vabits_actual value.
