Christophe JAILLET 09197d39ca drm/exynos: dsi: Remove bridge node reference in error handling path in probe function 
[ Upstream commit 547a734863 ]

'exynos_dsi_parse_dt()' takes a reference to 'dsi->in_bridge_node'.
This must be released in the error handling path.

In order to do that, add an error handling path and move the
'exynos_dsi_parse_dt()' call from the beginning to the end of the probe
function to ease the error handling path.
This function only sets some variables which are used only in the
'transfer' function.

The call chain is:
   .transfer
    --> exynos_dsi_host_transfer
      --> exynos_dsi_init
        --> exynos_dsi_enable_clock  (use burst_clk_rate and esc_clk_rate)
          --> exynos_dsi_set_pll     (use pll_clk_rate)

While at it, also handle cases where 'component_add()' fails.

This patch is similar to commit 70505c2ef9 ("drm/exynos: dsi: Remove bridge node reference in removal")
which fixed the issue in the remove function.
