Tomasz Bursztyka 86fde21f3b spi: Make the API fully synchronous
The driver has to implement the logic in an interrupt based manner.
Applying the changes to the existing drivers.

Changing ADC's API and implementation as well to follow those changes.

Andrew Boie d9cfbd5a61 interrupts: new static IRQ API
The interrupt API has been redesigned:

- irq_connect() for dynamic interrupts renamed to irq_connect_dynamic().
  It will be used in situations where the new static irq_connect()
  won't work, i.e. the value of arguments can't be computed at build time
- a new API for static interrupts replaces irq_connect(). it is used
  exactly the same way as its dynamic counterpart. The old static irq
  macros will be removed
- Separate stub assembly files are no longer needed as the stubs are now
  generated inline with irq_connect()

ReST documentation updated for the changed API. Some detail about the
IDT in ROM added, and an oblique reference to the internal-only
_irq_handler_set() API removed; we don't talk about internal APIs in
the official documentation.

Juan Manuel Cruz 11d2e57f90 adc: improves buffer management to hold repetitive reads.
ADC allows to program repetitives sampling after a read request.
User should be able to provide buffers for each table entry that can
hold subsequente repetitive samples.

Juan Manuel Cruz 42696ca14f adc: simplifies buffer management on adc dw driver.
Buffer management on dw driver was too complex.
New buffer management follows the following behavior.
- Each sequence entry have one sample at a time.
- Each sequence entry have a buffer to store that sample.
- If ADC have repetitive sampling configuration, the buffer value
  is overwritten with the new value.

New buffer management allow us to remove Synposys'
files and license headers as well.

Juan Manuel Cruz 46e79a7990 adc: adapts irq static macro calls
Adapts IRQ macro calls for the new IRQ static support convention
on ARC.

The new IRQ_CONNECT macro requires to receive the irq numbers without
parenthesis around. This is needed to execute preprocesor substitution
correctly.
