Optimize zinitix touch firmware upgrade flow

Browse source 
Found that zinitix touch firmware upgrade failed due to checksum
error,but now firmware version check right and touch works well.
It's not sram broken or burst upgrade problem, suspect "0x55aa"
check sum not stable.
Change the firmware check to a more stable way after burst upgrade.
