[PATCH v2 29/39] xen/riscv: add definition of __read_mostly

[Oleksii Kurochko <oleksii.kurochko@xxxxxxxxx>]

The definition of __read_mostly should be removed in:
https://lore.kernel.org/xen-devel/f25eb5c9-7c14-6e23-8535-2c66772b333e@xxxxxxxx/

The patch introduces it in arch-specific header to not
block enabling of full Xen build for RISC-V.
