[nrf fromtree] dts: common: nordic: nrf54l: Add hfpll clock source

Add 128 MHz clock source and use it for uart00. Baudrate setting must be adjusted based on uart clock source so without this change there is wrong baudrate on uart00. Signed-off-by: Krzysztof Chruściński <[email protected]> (cherry picked from commit 923d313)
