The code checks if any of the UART's is still transmitting.
If so then prevent from entering deepsleep

1. Use the updated API's provided by the SMC driver
2. Wait till debug UART has finished transmitting data

1. Fix the check to look for if MCG has a PLL
2. Do setup before and after deep sleep mode execution

Add sleep/deepsleep functions to platform layer which are replacing HAL
functions with the same name, rename existing symbols in HAL layer
to hal_sleep/hal_deepsleep. This way sleep functions
are always available, even if target doesn't implement them, which makes
the code using sleep clearer. It also enables us to make decision on in
which builds (debug/release) the sleep will be enabled.
