In function mtk_dsi_clk_hs_state, remove unnecessary conversion to bool return, this change is to make the code a bit readable.

This is likely clearer as
return tmp_reg1 & LC_HS_TX_EN;or even
static bool mtk_dsi_clk_hs_state(struct mtk_dsi *dsi) { return readl(dsi->regs + DSI_PHY_LCCON) & LC_HS_TX_EN; }
I like the second one.
