Laptops with any of the ppt or nv tunables default to the minimum setting
on boot so we can safely assume a stored value is correct.
This patch adds storing of those values in the local struct, and enables
reading of those values back. To prevent creating a series of byte holes
in the struct the "<name>_available" bool is removed and
`asus_sysfs_is_visible()` uses the `ASUS_WMI_DEVID_<name>` directly.

Use %u for u32 values. This applies to all sysfs_emits in this patch.

Thought checkpatch or the compiler would catch that. Done.
I've added your reviewed tag due to the simplicity of the change requested. I
hope this was okay.

Hi,
Please don't add Reviewed-by tags automatically in the future. Its
meaning is not that the person has looked the patch.
