Remove stm32f10x.xml, there are better described stm32f10x definitions in the STM32F10X_xx.xml that have
more accurate register maps as they have model variant specific registers
STM32F10X_CL.xml had non-standard "PLL input clock * X" descriptions. Standarize on "PLL input clock*X" to match
the other STM32F10X_YY.xml files
