Convert reset manager for Gen5, Arria 10 and Stratix 10 from struct to defines.

A commit message should describe what the commit does. By leaving out the fact that you're now loading the base address from DTS, you're not describing all changes.

As much as I hate to request a v3, could you please add this fact to the commit message?

Okay, will resend with commit message update in v4.

Regards Ley Foon

v3:

• Remove "No functional change" in commit description.

v2:

• Get base address from DT
• Revert to use writel(), readl(), setbits_le32() and clrbits_le32().
• Add prefix to defines.

Convert system manager for Gen5, Arria 10 and Stratix 10 from struct to defines.

Same as 2/4: please add a description about the "read address from dts" thing.

Regards, Simon

v3:

• Remove "No functional change" in commit description.

v2:

• Revert to use writel(), readl() and etc.
• Get base address from DT.
• Add prefix to defines.

Convert clock manager for Gen5, Arria 10 and Stratix 10 from struct to defines.

Same as 2/4: please add a description about the "read address from dts" thing.

Regards, Simon

v3:

• Remove "No functional change" in commit description.

v2:

• Revert to use writel(), readl() and etc.
• Get base address from DT.
• Add prefix to defines.
