bcm53xx: drop downstream patch that now breaks pinctrl driver

This fixes:
[    0.292536] ns-pinmux 1800c100.cru:pinctrl: invalid resource
[    0.298322] ns-pinmux 1800c100.cru:pinctrl: Failed to map pinctrl regs
[    0.305578] ns-pinmux: probe of 1800c100.cru:pinctrl failed with error -22

Linux 5.4.157 included commit 6d0b30784fcd9 ("Revert "pinctrl: bcm: ns:
support updated DT binding as syscon subnode"") which makes pinctrl
driver expect the old DT syntax.
Drop downstream patch switching pinctrl node to the invalidated syntax.

Fixes: 0b7311300b01d ("kernel: bump 5.4 to 5.4.158")
