STM32F469 incorrect PLL48CLK source

In the STM32F4 stm32_registry.h, for STM32F469/479, STM32_PLL48CLK_ALTSRC is incorrectly defined as STM32_PLLSAI_Q_CLKOUT, but should be STM32_PLLSAI_P_CLKOUT.

If fixed, would be great to get a 21.11.x backport, if possible.

Hi,

Fixed in trunk, the whole trunk will be back-ported to 21.11.5 "soon".
