Wei Hu(Xavier) a680f2f376 RDMA/hns: Add mailbox's implementation for hip08 RoCE driver 
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.

* roce_hw_index_cmp_lt - Compare two hardware index values in hisilicon
* SOC, check if a is less than b.
* @a: hardware index value
* @b: hardware index value
* @bits: the number of bits of a and b, range: 0~31.
*
* Hardware index increases continuously till max value, and then restart
* from zero, again and again. Because the bits of reg field is often
* limited, the reg field can only hold the low bits of the hardware index
* in hisilicon SOC.
* In some scenes we need to compare two values(a,b) getted from two reg
* fields in this driver, for example:
* If a equals 0xfffe, b equals 0x1 and bits equals 16, we think b has
* incresed from 0xffff to 0x1 and a is less than b.
* If a equals 0xfffe, b equals 0x0xf001 and bits equals 16, we think a
* is bigger than b.
*
* Return true on a less than b, otherwise false.
