More similar fixes like previous commits: handle the exceptional case
like ALC267 where no volume amp is found in ADC widget but in the
capsrc widget instead.
Also minor checks for avoiding possible erros: no connection-select
when the pin has a single selection, and add beep verbs only when the
0x1d is used for beep.

ALC259 seems to provide an invalid widget capability for the input-src
selector widget. The widget shows the input-amp while it's a selector,
and this confuses the current ALC882 initialization code that is used
for ALC259, too. For fixing this, check the amp capability and handle
the connection selection individually.
Also, ALC259 has no mute bit in DAC volume, so we need to initialize
it as ZERO instead of MUTE.

ALC269 and compatible codecs have the output volume in DACs, thus we
can't use the ALC880's code as is. Fixed by checking the amp caps and
picking up the right widget for initialization.

The Freescale hypervisor does not allow guests to write to the timebase
registers (virtualizing the timebase register was deemed too complicated),
so don't try to synchronize the timebase registers when we're running
under the hypervisor.
This typically happens when kexec support is enabled.

The Freescale ePAPR reference hypervisor provides interrupt controller
services via a hypercall interface, instead of emulating the MPIC
controller. This is called the VMPIC.
The ePAPR "virtual interrupt controller" provides interrupt controller
services for external interrupts. External interrupts received by a
partition can come from two sources:
- Hardware interrupts - hardware interrupts come from external
interrupt lines or on-chip I/O devices.
- Virtual interrupts - virtual interrupts are generated by the hypervisor
as part of some hypervisor service or hypervisor-created virtual device.
Both types of interrupts are processed using the same programming model and
same set of hypercalls.

ePAPR hypervisors provide operating system services via a "hypercall"
interface. The following steps need to be performed to make an hcall:
1. Load r11 with the hcall number
2. Load specific other registers with parameters
3. Issue instrucion "sc 1"
4. The return code is in r3
5. Other returned parameters are in other registers.
To provide this service to the kernel, these steps are wrapped in inline
assembly functions. Standard ePAPR hcalls are in epapr_hcalls.h, and
Freescale extensions are in fsl_hcalls.h.

The 'encrypted' key type defines its own payload format which contains a
symmetric key randomly generated that cannot be used directly to mount
an eCryptfs filesystem, because it expects an authentication token
structure.
This patch introduces the new format 'ecryptfs' that allows to store an
authentication token structure inside the encrypted key payload containing
a randomly generated symmetric key, as the same for the format 'default'.
More details about the usage of encrypted keys with the eCryptfs
filesystem can be found in the file 'Documentation/keys-ecryptfs.txt'.

A recently added feature to the firmware enables the driver to retrieve
firmware logs via the host bus (SDIO or SPI).
There are two modes of operation:
1. On-demand: The FW collects its log in an internal ring buffer. This
buffer can later be read, for example, upon recovery.
2. Continuous: The FW pushes the FW logs as special packets in the RX
path.
Reading the internal ring buffer does not involve the FW. Thus, as long
as the HW is not in ELP, it should be possible to read the logs, even if
the FW crashes.
A sysfs binary file named "fwlog" was added to support this feature,
letting a monitor process read the FW messages. The log is transferred
from the FW only when available, so the reading process might block.
