Function driver can register for card removal notifications.
Before removing the card, let function driver notify the same
and allow it to cleanup.

Add an API to enable/disable interrupts from the chip.
This API uses func0 SDIO_CCCR_IENx register to enable/disable
interrupts from the chip.

In case of LOGP recovery Wifi is soft reset. During soft reset,
observe that regulator_get() is not called for all regulators.
This is leading to null pointer dereference by kernel when
regulator_put() is called while turning of Wifi.

The WLAN driver votes for whatever the current it requires from
8901_s4.As it just loads L0 and LVS1, 60mA should be fine.

In 8660 wifi is using 8901 regulators. Once wifi is enabled and disabled
back, these regulator does not go in LPM mode and causing the device to
draw more current in suspend state. Hence put these regulator in LPM mode.

Wifi and BT have shared voltage regulator. So if both
needs to be enabled, there is a voltage level conflict
between them. In case of older vreg implementation
there is no such sanity check regarding the voltage
levels, hence no conflict.
But in case of regulator API's, it has a sanity check for
previously voted voltage for a particular regulator. Hence
in this case we need to pass the minimum & maximum voltage
range for both BT & WIFI, so that regulator framework will
internally set the common voltage level for both devices.

Set BT regulator voltage level in bluetooth_switch_regulator function.
It is used to make correct voltage level for BT, everytime BT is
turned off/on. Also set regulator voltage level for wifi for everytime
wifi is turned off/on.

Combine rpm-regulator.c and rpm-regulator-8960.c so that only a
single file named rpm-regulator.c contains the RPM regulator
driver logic. This will initially support both 8660 and 8960.
The data needed to capture the configuration of the RPM regulator
driver on different platforms will be added in platform specific
files.
