timers: atmel_pit: introduce CONFIG_SPL_ATMEL_PIT_TIMER

Browse Source 
This commit allows the ATMEL_PIT_TIMER driver to be unselected in SPL and be
selected in u-boot proper. The SPL can use a different timer.
By having a separate Kconfig for ATMEL_TCB in SPL, the size of the SPL
decreases by 0.3 KBytes.
