Add a option to select the memory alocation value for Flame Devices

[bebef1987]

It would be nice to have a option to set the memory allocation option from the flash tool

currently we need to run some other commands to set the memory allocation for the flame devices

#!/bin/bash -e
echo -e "\n\033[1mResetting memory allocation\033[0m"
adb reboot bootloader
fastboot oem mem $1
fastboot reboot
sleep 60
