[PATCH] clk: rockchip: rk3036: Add apll as the critical clock

[Xing Zheng]

The apll may be closed if there are some child clock nodes below
it when the device startup. Therefore, the apll should be keep
critical.

The apll tree like this:
    pll_apll
       apll
          armclk
             pclk_dbg
             aclk_core_pre
          aclk_hvec
          uart_pll_clk
             uart2_src
                uart2_frac
             uart1_src
                uart1_frac
             uart0_src
                uart0_frac
