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.

---
Changes in v3:
- Remove useless defines
- Add printf in case of unsupported timers specified in device-tree
- Add "syscon" compatible to tcb node

Changes in v2:

  timer: atmel_tcb_timer: add atmel_tcb driver
  ARM: dts: at91: sama5d2: add TCB node
  configs: sama5d2: enable option CONFIG_ATMEL_TCB_TIMER
