drm/msm/mdss: specify cfg bandwidth for SDM670 

stable inclusion
from stable-v6.6.48
commit ab7554fb515b4cf488feb99f972de91e8fc69953
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/IAWEBV

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=ab7554fb515b4cf488feb99f972de91e8fc69953



--------------------------------

commit 8d35217149daa33358c284aca6a56d5ab92cfc6c upstream.

Lower the requested CFG bus bandwidth for the SDM670 platform. The
default value is 153600 kBps, which is twice as big as required by the
platform according to the vendor kernel.
