USDHC1_FREQUENCY was a hand-maintained literal. Derive it from PLL2_PFD2_FREQUENCY (itself derived from ccm::analog::pll2::FREQUENCY and the bootloader-set PFD2 fractional divider) and a named USDHC1_PODF divider. Add a compile-time assert to catch any future drift.

Your comment about the clocks in CHANGELOG pushed my anxiety about USDHC1_FREQUENCY being a hand-maintained literal over the top.
