Only use SOC_AT91SAM9 for all the at91sam9 SoCs. It removes all the empty
at91sam9xxx.c SoC files. It also removes the useless at91_init_soc affectation
procedure and its "init" function pointer.
Only the SoC detection and display are kept for the at91sam9:
at91_soc_is_enabled() and at91_boot_soc.map_io() function calls are also
removed.

It enables HAVE_AT91_SMD and HAVE_AT91_UTMI for all the sam9 SoCs but this only
represents 96 bytes of uncompressed kernel code.

used to provide MCK for camera sensor.

We change its name to: pinctrl_pck1_as_isi_mck.

As we want camera sensor instead of ISI to configure the pck1 (ISI_MCK) pin.
So we remove this pinctrl from ISI DT node. It will be added in sensor's
DT node.
