[PATCH] gpio: adp5588-gpio: add i2c forward declaration

[Mike Frysinger]

From: Michael Hennerich <michael.hennerich@xxxxxxxxxx>

Some ADP5588 functions take a pointer to an i2c_client, but if the i2c
header doesn't happen to be included first, we hit the standard "struct
declared inside parameter list" warnings from gcc.  So add a simple
forward decl of the i2c_client struct.
