Hauke Mehrtens 18e6df83bb bcm47xx: Refresh kernel 5.15
This makes the patches and the kernel configuration apply on top of
kernel 5.15.

The following patch was removed because the old IDE subsystem was
removed from upstream kernel:
target/linux/bcm47xx/patches-5.15/610-pci_ide_fix.patch

This was tested successfully on a ASUS WL-500g Premium V1.

Subject: [PATCH v3 4/9] mtd: rawnand: brcmnand: Move OF operations out of brcmnand_init_cs()
Date: Fri, 07 Jan 2022 10:46:09 -0800
Content-Type: text/plain; charset="utf-8"
In order to initialize a given chip select object for use by the
brcmnand driver, move all of the Device Tree specific routines outside
of brcmnand_init_cs() in order to make it usable in a platform data
configuration which will be necessary for supporting BCMA chips.
No functional changes introduced.
