anvl: Updated u-boot, kernel and initramfs

Updated to the following versions:

u-boot: 716f9a148c4c74dc558ade7237674f4e39428fa3
initramfs: 2a949655d89703df74f9a8a96ab24866f9149a30
kernel: 10f3395f79f1369303dd9733d27674a66773cbc6

Note that installer no longer configures USB or
WLAN except during install mode. The distro
must now contain the kernel modules and WLAN
firmware. And the distro needs to configure USB
and WLAN otherwise there's no way to connect to
the device except over UART.

The location of distro kernel components are:

/boot/dtbs/anvl.dtb
/boot/vmlinuz-linux-anvl
/boot/initramfs-linux-anvl.img

And then modules and WLAN firmware in the usual
locations.
add initramfs components
Just updated the u-boot for initramfs support

u-boot: 716f9a148c4c74dc558ade7237674f4e39428fa3
kernel: 10f3395f79f1369303dd9733d27674a66773cbc6
Fix initramfs.conf paths

As this is run from the kernel source directory, assume we
have ../omap3-usb-boot-install available.
Add binary of usb-manager but don't use it yet

This allows charging the battery in initramfs.
Update WLAN firmware

Update to use version 14.66.35.p52:

Updated initramfs with WLAN firmware and usb-manager

This is to allow manually starting usb-manager for charging
in initramfs for now.
Merge branch 'master' into rootfs-enhancments
do not manually setup usb networking since we do that through a different method now
support any type of archive tar accepts and is able to autodetect
fix shellcheck warnings
