nx2: mirror uniform registers above UR27 below R216
Uniform registers have GPR mirrors only for UR0-UR27 (R216-R237,
R240-R245). Kirby Air Riders' graphics shaders load a 64-bit base into
UR28:UR29 (ULDC.64 UR28, c[0x0][0x510]) and address global loads with it
(4 programs). When a program uses UR28 or above, lower it again with those
registers mirrored just below R216 (UR28 at R(216 - n), n even so pairs
stay adjacent) and that range kept from the program's own registers;
other programs keep the same layout.
