[ Upstream commit c3d4e5b126 ]
platform_get_resource() may fail and in this case a NULL dereference
will occur.
Fix it to use devm_platform_ioremap_resource() instead of calling
platform_get_resource() and devm_ioremap().
This is detected by Coccinelle semantic patch.

[ Upstream commit aa37448f59 ]
pm_runtime_get_sync will increment pm usage counter even it
failed. Forgetting to pm_runtime_put_noidle will result in
reference leak in adsp_start, so we should fix it.

Move the clock list to adsp_pil_data, make the pdc_reset optional and
make the driver directly enable the xo, sleep and core clocks.
The three clocks are previously toggled through the clock controller,
but that means the same hardware block needs to be mapped in both
drivers. Making the remoteproc driver enable the clocks is a nop when
using the clock controller, but allow us to remove the clocks from the
clock controller.

In case of error, the functions devm_kcalloc() and devm_ioremap()
returns NULL pointer not ERR_PTR(). The IS_ERR() test in the return
value check should be replaced with NULL test.
Also removed -EPROBE_DEFER check since devm_kcalloc never return
this error.
