The shared uart-pll is on boot a child of the apll that can get changed by cpu frequency scaling. So move it away to the more stable gpll to make sure the uart doesn't break on cpu frequency changes. This turned up during the 4.11 merge-window when commit 6a171b29 ("serial: 8250_dw: Allow hardware flow control to be used") added general termios enablement making the uart on rk3036 change frequency and thus making it susceptible for the frequency scaling issue.
