Subject: [PATCH] Media: omap4iss: Enable RSZB and update resizer control

Enable RSZB functionality in the OMAP4 ISS driver. This change sets the RSZB system configuration register to enable the RSZB module. Additionally, it updates the resizer control by setting the RSZ_EN_EN flag as required. This change enhances the driver's capabilities and prepares it for future developments.
