[PATCH] platform/x86: ISST: Correct command storage data length

[Srinivas Pandruvada <srinivas.pandruvada@linux.intel.com>]

After resume/online turbo limit ratio (TRL) is restored partially if
the admin explicitly changed TRL from user space.

A hash table is used to store SST mail box and MSR settings when modified
to restore those settings after resume or online. This uses a struct
isst_cmd field "data" to store these settings. This is a 64 bit field.
But isst_store_new_cmd() is only assigning as u32. This results in
truncation of 32 bits.

Change the argument to u64 from u32.
