bluesleep: Implemented to support bluedroid

"#define BT_BLUEDROID_SUPPORT 1" -> support BlueDroid
"#define BT_BLUEDROID_SUPPORT 0" -> support BlueZ

Since BlueDroid does not use kernel space HCI driver now, we add the
below 2 /proc nodes to make BlueDroid able to send HCI events to
bluesleep driver.

write 1 to /proc/bluetooth/sleep/lpm -> equivalent to HCI_DEV_REG event
write 0 to /proc/bluetooth/sleep/lpm -> equivalent to HCI_DEV_UNREG event
write 1 to /proc/bluetooth/sleep/btwrite -> equivalent to HCI_DEV_WRITE event

This basic implementation is from tegra kernel.

bluesleep: unlock spin before controlling the hsuart power

Kernel might be in sleep to wait for rpm communication when it
controls the hsuart power. So should unlock the spinlock before
controlling the hsuart power.

bluesleep: Add debugmask to print the debug messages out

enum {
       DEBUG_USER_STATE = 1U << 0,
       DEBUG_SUSPEND = 1U << 1,
       DEBUG_BTWAKE = 1U << 2,
       DEBUG_VERBOSE = 1U << 3,
};

eg. if you wanto to see the messages for both suspend and btwake, set like below
echo 6 > /sys/module/msm_bt_sleep/parameters/debug_mask
