Subject: [PATCH 1/2] ARM: at91: fix link error

PM support for SAMA7G5 has been submitted to mailing list before SAMA7G5
soc support thus the SAMA7G5 was not present in AT91 Kconfig file at
that moment. SoC support for SAMA7G5 hasn't added the proper PM flags to
Kconfig thus the link error bellow:

arch/arm/mach-at91/sama7.o: In function `sama7_dt_device_init':
sama7.c:(.init.text+0x18): undefined reference to `sama7_pm_init'
make: *** [Makefile:1176: vmlinux] Error 1

Add proper flags to AT91 Kconfig file to solve the issue.

Fixes: 5617a08dd9e1 ("ARM: at91: pm: add pm support for SAMA7G5")
Fixes: 18d694ecd91e ("ARM: at91: add new SoC sama7g5")
