DNM: OpenCS, XperiaParts: Enable IMS by default

[shank03]

IMS will now by enabled by default. However, it won't reflect on dirty flash as the preference would be already stored in

Settings.System.getInt(context.getContentResolver(), /* pref key */ "cs_ims", /* default value */);

where /* default value */ was 0 previously.

PS: If some user haven't toggled IMS preference from Xperia Parts even once yet, then IMS will be enabled by default as mentioned above.

Please test and verify before merge :)
