xburst: Remove unmaintained target

Browse Source 
This target only supports kernel 3.18, which is not supported in OpenWrt
any more for multiple releases. It also looks like there is no active
maintainer for this target.
Remove the code and all the packages which are only used by this target.

To add this target to OpenWrt again port it to a recent and supported
kernel version.

From: Xiangfu <xiangfu@openmobilefree.net>
Date: Fri, 12 Oct 2012 09:46:58 +0800
Subject: [PATCH 1/6] qi_lb60: add nand spl support
The JZ4740 CPU can load 8KB from two different addresses:
1. the normal area up to 8KB starting from NAND flash address 0x00000000
2. the backup area up to 8KB starting from NAND flash address 0x00002000

Subject: [PATCH 2/6] qi_lb60: add software usbboot support
JZ4740 CPU have a internal ROM have such kind of code, that make
JZ4740 can boot from USB
usbboot.S can downloads user program from the USB port to internal
SRAM and branches to the internal SRAM to execute the program

Subject: [PATCH 4/7] ASoC: JZ4740: delay activation of the DAC to work around
a sound bug.
A proper fix of that bug would require a big rewrite of the driver,
which (I hope) will be done eventually.

This register controls the accuracy of the RTC. uC/OS-II use
the RTC as a 100Hz clock, and writes a completely wrong value
on that register, that we have to overwrite if we want a working
real-time clock.
