[RFC PATCH 16/38] arm64/sysreg: Extend the maximum width of a register and symbole name

32bit has multiple values for its id registers, as extra properties
were added to the CPUs. Some of these end up having long names, which
exceed the fixed 48 character column that the sysreg awk script generates.

For example, the ID_MMFR1_EL1.L1Hvd field has an encoding whose natural
name would be 'invalidate Iside only'. Using this causes compile errors
as the script generates the following:
 #define ID_MMFR1_EL1_L1Hvd_INVALIDATE_ISIDE_ONLYUL(0b0001)

Add a few extra characters.
