[PATCH v7 0/4] add TCB driver for sama5d2

[Clément Léger]

When booting under OP-TEE, the SYSC is secured which means the PIT is
also not accessible by non-secure world. The TCB 0 however is always
available for non-secure world and thus can be used.
This series add a TCB driver and enables it in sama5d2 configs.
