5.6.2-armv7-x9 patch adds ioremap_nocache which breaks the build #48

As the title says, the patch for 5.6.2 re-adds that unused function to /drivers/net/wireless/broadcom/brcm80211/brcmfmac/pcie.c , which breaks the kernel build. This is because Linux 5.6 removed ioremap_noncache:

remove ioremap_nocache and devm_ioremap_nocache ioremap has provided non-cached semantics by default since the Linux 2.6 days, so remove the additional ioremap_nocache interface.

Simply replacing ioremap_nocache with ioremap fixes the issue. This patch does this.

Thanks @Megver83 ! All merged (v5.6.x/v5.7.x branches)

I really wish we didn't have a brcmfmac wifi module on the beaglebone-ai, as we have to use the massive patchset to get SoftAp0 working on our module..
