b1f0a4ca4e USB: Delete mass storage driver
This was an attempt at providing support for flashing a
SPI flash device over USB, but it suffered from being
rather complex and large.  A simpler solution of bridging
SPI over USB directly and writing a SPI over USB driver
for flashrom is being used instead.

b5557217aa pd: dingdong/hoho: Fix hard reset recovery timeout.
dingdong/hoho have no capability to measure VBUS which is advantageous
in determining what timeouts to honor.  Previously we simply assumed
vbus was on and that made things happy until,

  e0c80ac pd: on hard reset go to a hard reset recovery state

which introduced proper handling around sink & source reset recovery.

With VBUS assumed 'on' this leads to short timeouts chosen
(PD_T_SAFE_0V) which in turn causes sink to resend hard resets before
source has had time (PD_T_SRC_RECOVER) to handle request.

This change creates config CONFIG_USB_PD_NO_VBUS_DETECT for devices
without the capability to account for lack of VBUS detect.

079742b1ff USB: Enable finer grain control over init process
Previously enabling USB would automatically (using an

take over the GPIO lines assigned to the USB module.

60ddb3987a samus: change hibernate delay to 7 days
Add macro for default hibernate delay, and set to 7 days on samus.
Also, adds CONFIG_ option for hibernating early if low on battery.
For samus, setting early hibernate at 1 day when battery < 10%.

BUG=chrome-os-partner:33088
BRANCH=samus
TEST=make buildall

Added ccprintf("Target shutdown: %.6ld\n", target_time); to print
out target shutdown time after setting it. Verifed the following
on samus

1) If CONFIG_HIBERNATE_DELAY_SEC is left at default 3600 (samus
board.h does not overwrite it), then target time is 3600s.
2) If CONFIG_HIBERNATE_DELAY_SEC is defined in samus/board.h, then
target time equals that value.
3) If CONFIG_HIBERNATE_DELAY_SEC is defined as 1 week and
CONFIG_HIBERNATE_BATT_PCT is defined to 10% and
CONFIG_HIBERNATE_BATT_SEC is 1 day, then when battery is between 8-10%
target time is 1 day and if battery is at 11%, target time is 1 week.

44e4f7cfe7 usb: Groundwork for USB BOS & Billboard class descriptors.
The BOS (Binary Device Object Store) descriptor was added to the USB
specification (3.0) to allow a richer set of device capability
specific descriptors.

The Billboard class is meant to expose (read-only) the status of USB
devices capable of alternate mode functions.  It's required to use the
BOS descriptor type and at a high level looks like:

  - BOS Device Descriptor (5bytes)
    - Container ID Device Capability Descriptor (20bytes)
    - Billboard Device Capability Descriptor (44byte + 4 * numSVIDs)

This CL adds:
1. Ability for Get Descriptor on BOS descriptors.  Note hidden behind
CONFIG_USB_BOS as these descriptors change USB device requirements
to:
   - bcdUSB >= 0201
   - no interface descriptors

2. structures for all BOS, Container & Billboard descriptor elements
complete w/ CamelCase.
