Subject: [PATCH] Caching service class updates during bootup.

From: Alok Barsode <[email protected]>

adapter->svc_cache is uses to cache service class updates during bluetoothd
bringup. adapter->cache_enable flag is used to switchoff the cache, so any successive
service class updates are directly written to the device.
