D+ is PA12 not PA11. The reason this worked before, is because the line
before made PA12 output, and without setting the GPIO_ODR register
_before_ hand, this meant as soon as it was switched to output, it
received the reset value of GPIO_ODR for PA12, ie, 0. (Effectively
doing a "free" gpio_clear(GPIOA, GPIO12)
Because GPIO11 wasn't configured to be an output, the confusing
gpio_clear(GPIOA, GPIO11) was simply configuring the pullup/down value
of the input, which was still ignored, as it was (out of reset) in input
floating mode.

Clearly staging branch testers weren't testing.
Also, clearly the separation of RST_ bits and RCC_ bits is a complicated
annoyance.
Fixes: d9615a2eb728 update to modern include apis
Added the CAN1 compatibility aliases as has been done for adc and dac to
make code reuse easier. Only for the magic enums, the raw bit
definitions remain as per the ref mans
Originally suggested as https://github.com/libopencm3/libopencm3/pull/802
the RCC_TIM17 and RCC_TIM18 macros used in the "new" style were ok, just
the old style raw bit definitions.

Use EP0 OUT flow control to NAK OUT packets when we're not yet expecting
any. This prevents the status OUT event from arriving while the control
state machine is still expecting the data IN completion event.
Attempt to be more brutal by delaying more often, instead of always
promptly servicing the usb stack.
This is implemented via using timer6 to do a known number of
microseconds busy delay, and so only works on platforms that have
reached at least core timer functionality, and provide the
rcc_apb1_frequency variable.
NOTE! This will _fail_ on devices using the st_usbfs drivers at present,
but the code _should_ work, and the tests land to verify that the
library fix, fixes the problem. (see subsequent commit)
rcc_osc_bypass_enable and rcc_osc_bypass_disable have been copy/pasted
around for the last time! There's a compile bit to check for L0/L1, but
otherwise this is just code duplication for no gain.

At least provide macros for each family that allows easy masking of the
full set of reset reason flags. Trying to provide a function that
provides these in random upper bits seems unclear at best.
Reserved bits are marked explicitly in the comments. ASCR defines
are changed to be consistent with the reference manual. HYSCR,
ASMR, CMR and CICR register defines are rewritten to be more
concise and readable.
