acpi/arm64: fix next_platform_timer() section mismatch error

Fix modpost Section mismatch error in next_platform_timer().

  [...]
  WARNING: modpost: vmlinux.o(.text.unlikely+0x26e60): Section mismatch in reference from the function next_platform_timer() to the variable .init.data:acpi_gtdt_desc
  The function next_platform_timer() references
  the variable __initdata acpi_gtdt_desc.
  This is often because next_platform_timer lacks a __initdata
  annotation or the annotation of acpi_gtdt_desc is wrong.
