chip/stm32/usb_hid_keyboard: Reload keyboard endpoint on reset
After the USB device is reset, force sending the keyboard data at
least once to make sure the host is aware of the curreny key/switches
status.
In particular, this is necessary for the host to be aware that we
are in tablet mode on host boot (this is not a problem on attach, as
other routines in the EC init sequence cause the endpoint to be
loaded anyway).
BRANCH=nocturne
BUG=b:117439202
TEST=Reboot nocturne with whiskers attached in tablet mode, see
that nocturne is still in tablet mode after reboot:
evtest --query /dev/input/event6 EV_SW SW_TABLET_MODE; echo $?
=> 10
