4fe04c84d4 drivers: dma: pl330: Zero initialize the ch_handle 
Zero initialize the ch_handle in dma_pl330_configure().
The memset in dma_pl330_config_channel()is incorrect,
as the ch_handle is already populated with valid values and
the dma_pl330_config_channel() is overwriting with zeros.

02703e60d9 device: Remove DEVICE_DT_DECLARE / DEVICE_DT_INST_DECLARE 
Now that we generate a header that extern's all possible devicetree
based device struct we can remove DEVICE_DT_DECLARE and
DEVICE_DT_INST_DECLARE as they aren't needed anymore.

e18fcbba5a device: Const-ify all device driver instance pointers 
Now that device_api attribute is unmodified at runtime, as well as all
the other attributes, it is possible to switch all device driver
instance to be constant.

A coccinelle rule is used for this:

@r_const_dev_1
  disable optional_qualifier
@
@@
-struct device *
+const struct device *

@r_const_dev_2
 disable optional_qualifier
@
@@
-struct device * const
+const struct device *

Fixes #27399
