Runtime PM lock init API right now returns pointer to a context
but this would cause confusion to the caller if feature is not
defined and dummy function return NULL as caller can't find real
failure versus dummy function returning because feature not being
enabled.
Fix declaring a data structure in QDF layer that caller can use
but it hides the internal details of HIF implementation for
Runtime PM locks.

hif_exec_context extends hif_ext_groups to support napi and tasklet models.
Some of the rename and enahancements have been done to support merging of
the execution context management code between the CE and DP contexts, as
well as supporting irq affinity for both napi & tasklet contexts.

To fix the following compilation error:
warning: assignment discards ‘const’
qualifier from pointer target type, at:
reg_table->section = ar6320v2_reg_table
in ol_fw.c.
It's because the register table is a
const array, while reg_table->section does
not point to a const.
So add 'const' for 'section'.

The hif_napi_info structure has a dummy netdev included.
The dummy netdev is large. Avoiding unneeded allocation
save 30kb of memory. Dynamically allocating the
hif_napi_info structures also reduces the size of

The existing HIF NAPI blacklist feature uses irq_blacklist_on(off) APIs
which make a call to the userspace irq_balancer.
Replace these APIs with kernel API irq_modify_status to mark (or unmark) the
individual interrupts with IRQ_NO_BALANCING flag. Once marked, the
msm-irq-balancer will not be able to move the CE interrupts around.

Interrupt blacklisting in kernel 4.4 happens through a user-space
entity. The kernel APIs irq_blacklist_on(off) essentially send
a message to the user space service(irq balancer) and
therefore are not synchronous and do not guarantee that blacklisting
has actually taken effect. It will be granted with some latency
(userspace entity's processing delay).
Make blacklisting more robust by:
a) move irq (if it has been moved around after blacklist_on call
has been made and not yet honored) to the designated CPU
on IRQ reception
b) stop cpu_isolation in blacklisting mode boost API
c) modify NAPI stats to indicate blacklisting mode
