gpu: drm: amdgpu: Replace mdelay with msleep in cik_pcie_gen3_enable()
cik_pcie_gen3_enable() is only called by cik_common_hw_init(), which is
never called in atomic context.
cik_pcie_gen3_enable() calls mdelay() to busily wait, which is not
necessary.
mdelay() can be replaced with msleep().
This is found by a static analysis tool named DCNS written by myself.
