msm: mdss: refactor ot limits to support rd and wr
Current code only supports to configure the same
read and write ot limits. For newer platforms it is
needed to configure different default limits for
each of the operations. This patch refactors the
implementation so the driver can support a different
default limit for the read and the write operations.
