Subject: [RFC PATCH 6/7] clk: mediatek: mt8173: Fix usage of mtk_clk_register_ref2usb_tx()

As part of the effort to improve the MediaTek clk drivers, the next step
is to switch from the old 'struct clk' clk prodivder APIs to the new
'struct clk_hw' ones.

The apmixed clk library contains one special clk type that doesn't fit
any of the generic clk types. This type is currently used only on the
MT8173 SoC. The code for this clk type was converted by the coccinelle
script from the previous patch, but the call site was not.

Fix the return variable type for mtk_clk_register_ref2usb_tx() in the
MT8173 clk driver.
