tpm: atmel: depend on X86
tpm_atmel probes for the chip at fixed x86 Super-I/O ports (0x4e) with inb()/outb(), so it only works on x86. TCG_ATMEL nevertheless depends only on HAS_IOPORT_MAP/HAS_IOPORT, which arm and arm64 also satisfy. There the probe is useless, and on platforms whose unbacked I/O access faults it oopses in init_atmel() at boot (e.g. arm/versatile): Unable to handle kernel paging request at virtual address fee0004e PC is at init_atmel+0x34/0x244 TCG_NSC and TCG_TIS already "depends on X86" (commit 2f592f2a7d74 ("TPM: NSC and TIS drivers X86 dependency fix")); TCG_ATMEL was missed. Add the same dependency.
