This reverts commit d39083234c.
Because of recent interactions with developers from @umn.edu, all
commits from them have been recently re-reviewed to ensure if they were
correct or not.
Upon review, it was determined that this commit is not needed at all as
the media core already prevents memory disclosure on this codepath, so
just drop the extra memset happening here.

Commit b2d3bef1aa ("media: coda: Add a V4L2 user for control error
macroblocks count") add the control for the decoder devices. But
during streamon() this ioctl gets called for all (encoder and decoder)
devices and on encoder devices this causes a null pointer exception.
Fix this by setting the control only if it is really accessible.

Smatch is warning that:
drivers/media/platform/qcom/venus/hfi_venus.c:1100 venus_isr() warn: variable dereferenced before check 'hdev' (see line 1097)
The logic basically does:
hdev = to_hfi_priv(core);
with is translated to:
hdev = core->priv;
If the IRQ code can receive a NULL pointer for hdev, there's
a bug there, as it will first try to de-reference the pointer,
and then check if it is null.
After looking at the code, it seems that this indeed can happen:
Basically, the venus IRQ thread is started with:
devm_request_threaded_irq()
So, it will only be freed after the driver unbinds.
In order to prevent the IRQ code to work with freed data,
the logic at venus_hfi_destroy() sets core->priv to NULL,
which would make the IRQ code to ignore any pending IRQs.
There is, however a race condition, as core->priv is set
to NULL only after being freed. So, we need also to move the
core->priv = NULL to happen earlier.

An upcoming silicon change places a number of existing blocks within the
Venus at different relative offsets to the base address of IO region.
In order to handle this difference this patch changes the address offsets
of the registers to function as offsets relative to the relevant sub-block
of registers within the IO region not the base address of the IO region.
As a result of this change venus_readl() and venus_writel() are deleted.
