[PATCH v2 0/4] Fix rtl8169 compile warning and add a new device ID

[Minda Chen]

StarFive JH7110 uboot support PCIe and using rtl8169 network adapter
PCIe device. But compile warning in rtl8169 driver cause CI test fail.
So commit this patch set to fix it, Also a new device ID to adjust the
PCI bar regions in rtl8169.

The StarFive JH7110 PCIe driver link, patch 4 rely on this.

previous version:
[1] https://patchwork.ozlabs.org/project/uboot/cover/20230621090540.119313-1-minda.chen@starfivetech.com/

change:
v2: patch 1- 3 modify the commit messages.
    rebase to latest mainline codes.

patch 1 is fix make pointer from integer warning.
 eg: /home/minda/vf2/visionfive/u-boot/drivers/net/rtl8169.c:103:52: warning:
    passing argument 2 of ‘writew’ makes pointer from integer without a cast [-Wint-conversion]
patch 2 fix RISC-V 8169 descriptor less than DMA min aligned size warning
patch 3 add new device ID
patch 4 enable 8169 in JH7110 SoC configs file.

[PATCH v2 1/4] net: rtl8169: Fix compile warning in rtl8169

[Minda Chen]

While compiling rtl8169.c, There are many "make pointer from
integer without a cast" compile warnings. fix them with
adding cast.

[PATCH v2 2/4] net: rtl8169: Fix DMA minimal aligned compile warning in RISC-V

[Minda Chen]

For RISC-V architeture, hardware maintain the dcache coherency.
Software do not flush the cache. So even cache-line size larger
than descriptor size, driver can work.
