What commit does this fix? Should it go to stable kernels? Please put
that in here if needed.

It has not yet been revealed that this is a bug. The reason I changed it
was because I thought it was an improvement and it might be a hidden
bug.The AML_UART_TX_EN bit is conspicuously missing when comparing the
meson_uart_shutdown and meson_uart_startup functions.So I think it's
best to add.
