[PATCH v2 2/2] resource: Make it possible to reserve memory on 64bit platform

[Wesley Zhao]

For now "reserve=" is limitied to 32bit,not available on 64bit
platform,so we change the get_option() to get_option_ull(added in
patch: commit 4b6bfe96265e ("lib/cmdline: add new function
get_option_ull()"))
