Some USB interface handlers need to know when USB has been
successfully resumed after a wake event. For example, this is
useful so that HID keyboard can send the events at the right time.

TEST=Using USB HID keyboard patches to queue keys in a FIFO:
After USB autosuspends, press a single key and hold it. Without
this patch the endpoint data only gets reloaded on the _next_
event.
TEST=On hammer, I2C passthrough still works.

Add support to write and erase all flash with flashrom.
Add support to use all the memory.
Note that PSTATE must not used its own page, as the STM32F4 use big pages.

BRANCH=none
TEST=With flashrom, write all, RO, RW regions.
Use flash command on the console, including flashwp

stm32f446 uses a synopsys designware USB block
rather than the typical ST one. This change adds driver support
for the new block, including usb console support.

stm32f446 has two types of i2c blocks, the traditional
stm i2c, and "fast mode plus" i2c, which need different drivers.
This commit adds both, muxed in i2c-stm32f4, as the ec
codebase doesn't really support multiple types of the same interface.
BUG=chromium:608039
TEST=i2c works on all 4 channels
