omapfb: dss: Handle return errors in dss_init_ports()

[ Upstream commit 0348aaa34412e24ebe622a2b1b013e68d6ae5412 ]

dss_init_ports() is not handling return errors from dpi_init_port() and
sdi_init_port(). It is also always returning 0 currently which results in
part of error handling code in dss_bind() being unused.

Fix dss_init_ports() to handle return errors from dpi_init_port() and
sdi_init_port().
