[U-Boot] [RFC] ipu_common: Let the MX6 IPU clock be calculated in run-time
From: Fabio Estevam fabio.estevam@nxp.com
MX6Q/QP IPU operates at 264MHz and MX6DL IPU at 198MHz.
When running a SPL target, which supports multiple MX6 variants we cannot properly setup the IPU clock frequency via CONFIG_IPUV3_CLK option as such decision is done in build-time currently.
Remove the CONFIG_IPUV3_CLK option and let the IPU clock frequency be detected in run-time on mx6.
