Subject: [PATCH] drm/tegra: sor: No need to free devm_ allocated memory

'brick' has been allocated by 'devm_kzalloc', so there is no need here to
free it explicitly.
There is only one caller of 'tegra_clk_sor_brick_register()'. This function
is a probe function which correctly checks and handles the return value of
'tegra_clk_sor_brick_register()'.
