[PATCH -next] HID: intel-ish-hid: fw-loader: Fix build error

[YueHaibing]

drivers/hid/intel-ish-hid/ishtp-fw-loader.c:1067:4: error: initializer element is not constant
  { loader_ishtp_guid },
    ^~~~~~~~~~~~~~~~~

The reason is that we are using non-const expressions to initialize the
static structure, which will probably trigger a compiling error/warning
on gcc-7.5.0. Fix it by converting const variable into macro.

Fixes: 44e2a58cb880 ("HID: intel-ish-hid: fw-loader: only load for matching devices")
