drivers: usb: udc: stm32: configure OTGFS/HS RxFIFO size using Kconfig
Create a new Kconfig option allowing to tweak the RxFIFO size on OTG_FS
and OTG_HS instances, and replace the old hardcoded method with this new
mecanism.
The default value of 600 bytes yields a similar size to the the previous
hardcoded default of 160 words (= 640 bytes) when combined with the fixed
overhead computed by the driver (~56 bytes on OTG_FS with 6 endpoints).
Also fix a tiny error in a logging message (DRAM size in bytes, not bits).
