Subject: [PATCH AUTOSEL 4.19 365/671] clk: meson: gxbb: no spread spectrum on mpll0

From: Jerome Brunet <jbrunet@...libre.com>

[ Upstream commit 8925dbd03bb29b1b0de30ac4e02c18faf8ddc9db ]

The documentation says there is an SSEN bit on mpll0 but, after testing
it, no spread spectrum function appears to be enabled by this bit on any
of the MPLLs.

Let's remove it until we know more
