In hip08 SoC, the hardware implementation of mailbox command
has changed with hip06 SoC. As a result, it adjusts the
architecture of the command code and implements the interfaces
of mailbox for hip08 SoC.

In order to support the scalability of the hardware version, the
features irrelevant to the hardware will be located in the hns-roce.ko,
and the hardware relevant operations will be located in hns_roce_hw_v1.ko
or hns_roce_hw_v2.ko based on the series chips.
The hip08 RoCE engine is a PCI device, hip06 RoCE engine is a platform
device. In order to support both platform device and PCI device, We
replace &hr_dev->pdev->dev with hr_dev->dev in hns-roce.ko as belows:
Before modification:
struct device *dev = hr_dev->dev;
After modification:
struct device *dev = &hr_dev->pdev->dev;
The related structure:
struct hns_roce_dev {
...
struct platform_device *pdev;
struct pci_dev *pci_dev;
struct device *dev;
...
}

The hardware relevant definitions and operations are implemented
in hns_roce_hw_v* file. According to the diversity chips, the file
is named as hns_roce_hw_v1.c or hns_roce_hw_v2.c etc.
The general software process flow, common structures and allocated
algorithms are implemented in other files located in hns roce driver.
In order to support the scalability of the hardware version, the
common driver features are in the hns-roce.ko, and the hardware
relevant operations are in hns_roce_hw_v1.ko or hns_roce_hw_v2.ko
based on the series chips.

* A multiplication for the size determination of a memory allocation
indicated that an array data structure should be processed.
Thus use the corresponding function "kmalloc_array".
This issue was detected by using the Coccinelle software.
* Replace the specification of a data structure by a pointer dereference
to make the corresponding size determination a bit safer according to
the Linux coding style convention.
