Subject: [net-next 3/7] can: m_can: m_can_config_endisable(): remove double clearing of clock stop request bit

From: Sean Nyekjaer <sean@...nix.com>

The CSR bit is already cleared when arriving here so remove this section of
duplicate code.

The registers set in m_can_config_endisable() is set to same exact values as
before this patch.
