yosemite4n: u-boot: Add patch to set memory test result in environment

Summary:
Add patch to set memory test result in environment after doing mtest
in u-boot so that user can check the result in user space. This patch
is needed by Wiwynn factory test.

Test Plan:
Set mtest command and reboot to check the memory test result.

root@bmc:~# fw_setenv preboot 'mtest 0x80000000 0x9A500000 0 1'
root@bmc:~# reboot
root@bmc:~# fw_printenv memtest_result
memtest_result=pass
