Among implemented STM32L4x5 devices, USART, GPIO and SYSCFG
have a clock source, but none has a corresponding test in QEMU.

This patch makes sure that all 3 devices create a clock,
have a QOM property to access the clock frequency,
and adds QTests checking that clock enable in RCC has the
expected results.
