gpio: uapi: clarify using v2 rather than v1

Browse Source 
The documentation contains notes like
 This struct is part of ABI v1 and is deprecated.
 Use struct gpio_v2_line_info instead.

This could be interpreted to mean the structs can be directly
substituted in v1 calls.  Clarify that the user should use the
corresponding v2 ioctl() and structs.
