net: hns3: fix hns3 driver header file not self-contained issue

The hns3 driver header file uses the structure of other files, but does
not include corresponding file, which causes a check warning that the
header file is not self-contained.

Therefore, the required header file is included in the header file, and
the structure declaration is added to the header file to avoid cyclic
dependency of the header file.

net: hns3: uniform parameter name of hclge_ptp_clean_tx_hwts()

The parameter name of hclge_ptp_clean_tx_hwts() in declaration is "dev",
but the definition of this function is used the common name "hdev" as
other functions, so modify it.

net: hns3: change the method of obtaining default ptp cycle

The ptp cycle is related to the hardware, so it may cause compatibility
issues if a fixed value is used in driver. Therefore, the method of
obtaining this value is changed to read from the register rather than
use a fixed value in driver.

net: hns3: fix a double shift bug

These flags are used to set and test bits like this:

if (!test_bit(HCLGE_PTP_FLAG_TX_EN, &ptp->flags) ||

The issue is that test_bit() takes a bit number like 1, but we are
passing BIT(1) instead and it's testing BIT(BIT(1)). This does not
cause a problem because it is always done consistently and the bit
values are very small.
