Auto negotiating console speed could cause sonic to lock on a wrong
speed under rare conditions. The only way to come out of the wrong
speed is to issue line break or restart console service with forced
speed, or reboot sonic.
Lock down the console speed to avoid these situations.

Flashes used for the 7050QX-32 and 7050QX-32S have a fw issue.
The best option to solve the problem is to upgrade to a newer firmware.
However this can only be done while in memory and take 10 seconds.
Adding an upgrade mechanism is possible but would need more
consideration as flashing the firmware and reformating the flash will
exceed the fast-reboot requirements.
A quick mitigation is to align the ext4 partition that we create on
these vfat based system on a 4k boundary.
Here we chose 1M instead but it's the same.
Newer version of sfdisk do this automatically but the one in SONiC
today doesn't have this behavior.
This workaround will only reduce the pace of the flash health
degradation. The only long term fix is to flash the firmware.

- Correct lane map in broadcom configuration
- Add writes to txdisable bits for SFPs in hwsku-init
- Add correct hwsku-init implementation for 201803 branch
- Introduced systemd .service files to start and stop platform drivers.
- Moved depmod in *.postinst files. So, during first-time boot depmod is triggered post package installation and drivers will be loaded without any issues.

On overlay filesystem the name of the mountpoint will also match in the
mount command for overlayfs as upperdir=
To prevent detecting the wrong partition we now look for space before.
This ensure that we match mountpoint and not devices in df and mount
outputs.
debian/rules should be 755 and will be modified to 755 if not, which
can cause the image to be marked as dirty

TODO:
Ideally, we should have ECN/WRED profile applied at per interface per queue
granularity, and we should do it for all hwskus under the device
directory, not just 7050.
