STM32C071 have USB peripheral which can be clocked from HSI (HSIUSB48). Signed-off-by: Tomáš Juřena <jurenatomas@gmail.com>
Allow to use internal HSI to clock the USB bus if HSE is not available. Signed-off-by: Tomáš Juřena <jurenatomas@gmail.com>
Enables the HSIUSB48 clock (node clk_hsi48 in the SoC DTSI) on the nucleo_c071rb platform. Signed-off-by: Tomáš Juřena <jurenatomas@gmail.com>

Create an HSI48 clock source (HSIUSB48) for the STM32C071 SOC. Only the STM32C071xx SOC supports this clock, and it can be used in systems which do not have an HSE or the HSE value is not 48 MHz.
