libpayload/arch/arm64/mmu: Specify ttb_buffer section name explicitly 

Although a section ".bss.ttb_buffer" is created automatically for
'ttb_buffer' with the GCC option '-fdata-sections', specify the section
name explicitly to make the name stand out to code readers, and to
reduce the chance of accidentally changing the section name by renaming
the variable.
