Kconfig: extend default PLL configuration for all STM32F4 chips
Kconfig: extend default PLL configuration for all STM32F4 chips

The default configuration will result in 84MHz system clock for
STM32F401, STM32F410 and STM32F411 or 168MHz system clock for other
chips from STM32F4 family. The default configuration keeps USB clock
(PLL "/Q" output) at 48MHz, that's why it's not possible to set 100MHz
for STM32F410 and STM32F411 or 180MHz for STM32F42, STM32F43, STM32F44,
STM32F46 and STM32F47 chips.
