When LTO is enabled, linker may relocate literal pools out of Thumb LDR instruction's reach causing "offset out of range" errors while linking. This commit adds `.ltorg` directive in the inline asm blocks where absolute addresses are loaded using the `ldr` instructions, in order to ensure that the literal pool containing the absolute addresses are placed near the `ldr` instructions. Note that the `.ltorg` directive is recognised by all toolchains supported by Zephyr and no toolchain abstraction is provided for now.
