[PATCH] RISC-V: ACPI: fix two __iomem cast warnings

[Ben Dooks <ben.dooks@codethink.co.uk>]

The __acpi_map_table() and __acpi_unmap_table() return and
take __iomem tagged pointers. Add a cast to fix the sparse
warnings:

arch/riscv/kernel/acpi.c:216:30: warning: incorrect type in return expression (different address spaces)
arch/riscv/kernel/acpi.c:216:30:    expected void [noderef] __iomem *
arch/riscv/kernel/acpi.c:216:30:    got void *
arch/riscv/kernel/acpi.c:224:24: warning: incorrect type in argument 1 (different address spaces)
arch/riscv/kernel/acpi.c:224:24:    expected void *addr
arch/riscv/kernel/acpi.c:224:24:    got void [noderef] __iomem *map
