MIPS: SGI-IP27: Fix platform-device leak in bridge_platform_create()

[ Upstream commit 11bec9cba4de06b3c0e9e4041453c2caaa1cbec1 ]

In error case in bridge_platform_create after calling
platform_device_add()/platform_device_add_data()/
platform_device_add_resources(), release the failed
'pdev' or it will be leak, call platform_device_put()
to fix this problem.

Besides, 'pdev' is divided into 'pdev_wd' and 'pdev_bd',
use platform_device_unregister() to release sgi_w1
resources when xtalk-bridge registration fails.
