* ApiHal: console abstraction, change uart baud rate to 230400. Bootloader: drop F5. Furi: prevent thread local output to serial console in stdglue. * ApiHal: take control over system initialization, reorder some subsystems in a hope of fixing USB issues. * Main: cleanup dead code. ISR: take care of HSECSS by our self. USB: leave clock configuration alone. * F6 cube: switch RCC to LL. * Cli: rollback return behavior.
