Make sure to keep UART clocks enabled during kernel init if earlyprintk or earlycon are active.

I prefer to code it like:
static struct clk **uart_clks[] __initdata = {
&clk[uart_ipg_per],
&clk[uart1_ipg],
&clk[uart2_ipg],
&clk[uart3_ipg],
&clk[uart4_ipg],
&clk[uart5_ipg],
NULL
};
Other than that, I'm fine with the series.
