irqchip/gic-v3: Add Rockchip 3588001 erratum workaround

Rockchip RK3588/RK3588s GIC600 integration does not support the
sharability feature. Rockchip assigned Erratum ID #3588001 for this
issue.

Note, that the 0x0201743b ID is not Rockchip specific and thus
there is an extra of_machine_is_compatible() check.

The flags are named FORCE_NON_SHAREABLE to be vendor agnostic,
since apparently similar integration design errors exist in other
platforms and they can reuse the same flag.
