arm64: dts: amlogic: t7: use the real UART pclk
uart_a listed the 24MHz crystal for all three of its clocks because the
T7 clock controller driver did not exist when these boards were added.
That leaves the real UART bus clock without a user, so the kernel
turns it off when it disables unused clocks at the end of boot, and
the board hangs.
Update the board DTS files to point uart_a's pclk to CLKID_SYS_UART_A
instead of the dummy crystal clock.
