Drop the __initdata for acpi_gtdt_desc variable to fix the section mismatch,

WARNING: modpost: vmlinux.o(.text.unlikely+0x95ac): 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.

I prefer to make this function as no inline, and make it
as __init function, becasue acpi_gtdt_desc is not used after
gtdt_sbsa_gwdt_init().

Thanks
