[2/5] drm/meson: Simplify usage of clk_rate_exclusive_get()

Commit Message

clk_rate_exclusive_get() returns 0 unconditionally. So remove error
handling. This prepares making clk_rate_exclusive_get() return void.

Hello,

btw, the driver fails to call clk_rate_exclusive_put() in the error
paths of dw_mipi_dsi_phy_init().

Best regards
Uwe
