[PATCH] dt-bindings: regulator: fan53555: add tcs,tcs4526

[Rudi Heitbaum <rudi@heitbaum.com>]

The driver has accepted tcs,tcs4526 since commit 5eee5eced95f
("regulator: fan53555: add tcs4526"), which added the compatible to both
the of_device_id and i2c_device_id tables for the TCS4526, a chip that
reports id 0 rather than the TCS4525's id 12.

The binding was converted to DT schema afterwards, in commit 6cea468b680e
("regulator: dt-bindings: Convert Fairchild FAN53555 to DT schema"), and
only picked up tcs,tcs4525. No in-tree DTS used the 4526 string at the
time, so nothing flagged the omission.

RK3399Pro boards use the TCS4526 for vdd_gpu and vdd_cpu_b, so a DTS
describing them fails dtbs_check today even though the driver binds
correctly.

Add the missing compatible.
