First look for a custom linker file defined by a config variable, if
not defined, look in the board directory. Finally look in the SoC
directory.
This adds flexibility and enhances modularity allowing a board to define
the linker the script instead of the SoC specific one.

Too many entries were being created in this table. It needs to
create indexes starting from 16 to CONFIG_NUM_IRQS - 1, since IRQS 0-15
are reserved for CPU exceptions and are not handled through this
mechanism.
generic_arc was still using the old C-based table which is
incompatible with the static IRQ implementation. An attempt was made
to move the SW IRQ table to arch/arc/core, but linker issues were
encountered and this will be done in another patch.
With CONFIG_NUM_IRQS set to 68 on Quark SE, inspection of binary
with objdump -x reveals that we are generating table entries:
00000000 g O .isr_irq16 00000000 _sw_isr_table
00000000 w O .gnu.linkonce.isr_irq16 00000000 _isr_irq16
00000000 w O .gnu.linkonce.isr_irq17 00000000 _isr_irq17
00000000 w O .gnu.linkonce.isr_irq18 00000000 _isr_irq18
...
00000000 w O .gnu.linkonce.isr_irq67 00000000 _isr_irq67
Which is exactly what we need.

CONFIG_NUM_IRQS expresses the total number of available interrupt
lines in the system, and is used to generate a vector table.
On ARC, the vector table is assembled from two parts, _VectorTable
for the first 16 entries (reserved for CPU exceptions), and
_IrqVectorTable for the remainder. The code that creates _IrqVectorTable
was not taking this into consideration and was 16 entries too big.

On ARC the IRQ and exception vectors are just one big array of
function pointers placed at the very beginning of the binary in ROM.
Vectors 0-15 are for CPU exceptions, 16-255 for interrupts.
In Zephyr these have been logically split into an execption table
followed immediately by the IRQ table, specified in the ARC linker.cmd.
However, the exception vector table defined in Zephyr had only 14
entries so the IRQ table was misaligned by 8 bytes. This went undetected
for some time as in the default configuration every entry in the IRQ
table pointed to the common demux function _isr_enter().
This patch correctly ensures that the IRQ table begins at address
0x40000040 instead of 0x40000038 like it had been.

Even though the OS is 32-bit, 64-bit BARs can still be mapped into
32-bit address space.
64-bit BARs occupy two entries instead of one, so the offset of a BAR
isn't necessarily its index multiplied by 4. To cope with that, hold an
extra offset field in the lookup structure.
Only 3 bits are required for index as well as the offset since the there
are up to 6 BARs.
