drivers: (le)u(s)art_gecko: use DT defined clock identifiers

Browse source 
Use the device tree to assign the correct peripheral clock to each
UART/USART/LEUART. Previously, the clock identifier was determined
through the sequence number of the instantiated UART. This meant
configuring all UARTs when only one of the later UARTs was required.
