Static interrupts rely on a trick where the _sw_isr_table array
is declared with each element in a different .gnu.linkonce
section, initially pointing to the spurious IRQ handler.
When drivers or apps declare their own interrupts, they override
the element with their own containing the real ISR and parameter.
However, this only works if the initial declaration of the
_sw_isr_table array with the spurious handlers is linked last.
App-specific code was being linked later than the core code,
causing static interrupts declared in apps not to be installed
correctly.
If the _sw_isr_table is moved from SOC-specific code to core arch
code, interrupts configured under soc/ should still also work.

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.

Avoid having to remove quotes wherever the platform name is used
by exporting the variable only once.

Do not repeat the same flags for every added platform. Define
the common flags on the architecture level instead.

Use CONFIG_PLATFORM to only build the selected platform. This
will enable support for drop-in platforms. Makefile will not need
to be changed for every new platforms.

Follow the model of the Linux kernel for adding arch
specific CFLAGS by using the Makefile and Kbuild combination
in the arch/<arch> directory.
This will also allow adding architecture specific targets and is
easy to maintain when alongside the architecture.
