Andrew Boie 4f0f7e3325 ipm_quark_se: don't wait for response with interrupts locked
If the remote handler tries to send a message back with wait enabled
it can lead to a deadlock.

Andrew Boie 08d3cd7bfd ipm: quark_se: fix dropped/repeating characters
The while loop on the status bit was unnecessary as we will get
a separate invocation of the ISR for every message. We also ensure
that the global status register bits for the channel being serviced
are cleared before exiting. Fixes an issue where some messages
would be dropped or repeated.

Some runtime checks that shouldn't happen in practice have been moved
to assertions.

Anas Nashif 10bb38c186 Use SoC instead of platform.
Change terminology and use SoC instead of platform. An SoC provides
features and default configurations available with an SoC. A board
implements the SoC and adds more features and IP block specific to the
board to extend the SoC functionality such as sensors and debugging
features.

Andrew Boie 3589695508 ipi: rename to ipm
To many people, IPI connotes inter-processor interrupts on SMP
systems. Rename this to IPM, or Inter-Processor Mailboxes.
