This commit removes unnecessary CONFIG_SYS_POWER_DEEP_SLEEP protection
in shim drivers as QMSI 1.4 has introduced empty context save/restore
functions that can be called in Quark D2000, therefore keeping common
code at the shim driver level for Quark SE and D2000.

Qiu Peiyang b549e0fbca spi_qmsi_ss: add device_busy_set() to avoid re-enter deep sleep
When CONFIG_SYS_POWER_DEEP_SLEEP is enabled, spi_qmsi_ss will
keep entering deep sleep because it needs to wait until the
current transfer completes, which blocks the current thread.
The system keeps entering deep sleep again and again and the
transfer will never complete.

Add device_busy_set() to spi_qmsi_ss driver to indicate that
the device is busy and block the system from entering deep
sleep during transaction.

Baohong Liu e1153004f9 drivers: spi_shim: grant arc the access to spi on I/O fabric
Enable arc to access the spi controller on I/O fabric.

There are two spi controllers on quark se SoC. One is attached
to the I/O fabric and the other one is in the sensor system.
X86 cpu is only able to access the spi controller on the I/O
fabric and the access is supported by existing code. HW allows
arc to access both controllers. But, the existing code only
gives arc access to the controller in the sensor sub-system.
Let's grant arc the access to the controller on I/O fabric as
well by the following changes.

1. Add spi_qmsi.c into arc compilation.
2. Use the already defined macros to choose interrupt numbers
   and do interrupt unmasking automatically based on the
   compilation targets.
3. Add new symbols in Kconfig including driver names for both
   controllers

Johann Fischer 212f5f28ed drivers: spi_k64: Fix RX overflow
This patch fixes RX overflow error in the k64 SPI driver.

Jira: ZEP-1351
Jira: ZEP-1352

Several circumstances lead to an RX overflow:

The RFOF_RE (RX fifo overflow) must not be set as default.
The flag is only set when rx_buf is available. Also it must
be checked inside spi_k64_isr whether RFOF_RE has been set or not.

If the rx_buf is not available and the incoming data
should be ignored, then MCR_ROOE need to be set.
Since it is not possible to change the MCR register
during the transfer, RX fifo must be emptied
if rx_buf_len < tx_buf_len.

The driver also uses spi_data.xfer_len now,
the variable was already defined. Now, transfers are also
possible if tx_buf_len < rx_buf_len (e.g. read slave device register).
spi_k64_push_data has been adjusted accordingly.

The patch simplifies the handling of interrupts.
The interrupts are also switched off in the event of an error.

The patch also fixes a few coding style issues.
