drivers/clock_control: stm32f1: Deal with stm32f100xx devices

Browse source 
According to RM0041.pdf clock tree for stm32f100xx devices is
different from both STM32F10X density and connectivity lines devices,
but is a combination of both.

Rework symbols definitions so that STM32F100xx is neither of those
and uses:
- CLOCK_STM32_PLL_MULTIPLIER as on SOC_STM32F10X_DENSITY_DEVICE
- CLOCK_STM32_PLL_PREDIV1 as on SOC_STM32F10X_CONNECTIVITY_LINE_...
