net: ti: icss-iep: fix setting counter value 

stable inclusion
from stable-v6.6.2
commit 98a52692167b9d863ec2325a43c2b79fcef7b274
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/I8IW7G

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=98a52692167b9d863ec2325a43c2b79fcef7b274



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

[ Upstream commit 83b9dda8afa4e968d9cce253f390b01c0612a2a5 ]

Currently icss_iep_set_counter() writes the upper 32-bits of the
counter value to both the lower and upper counter registers, so
fix this by writing the appropriate value to the lower register.
