pinctrl: nomadik: Drop U8540/9540 support 

The U8540 was an evolved version of the U8500, but it was never
mass produced or put into products, only reference designs exist.
The upstream support was never completed and it is unlikely that
this will happen so drop the support for now to simplify
maintenance of the U8500.

/*
* this table translates what's is in the AB9540 specification regarding the

* ALTERNATE_FUNCTIONS(GPIO_NUMBER, GPIOSEL bit, ALTERNATFUNC bit1,
* ALTERNATEFUNC bit2, ALTA val, ALTB val, ALTC val),
*
* example :
*
* ALTERNATE_FUNCTIONS(13, 4, 3, 4, 1, 0, 2),
* means that pin AB9540_PIN_D18 (pin 13) supports 4 mux (default/ALT_A,
* ALT_B and ALT_C), so GPIOSEL and ALTERNATFUNC registers are used to
* select the mux. ALTA, ALTB and ALTC val indicates values to write in
* ALTERNATFUNC register. We need to specifies these values as SOC
* designers didn't apply the same logic on how to select mux in the
* ABx500 family.
*
* As this pins supports at least ALT_B mux, default mux is
* selected by writing 1 in GPIOSEL bit :
*
* | GPIOSEL bit=4 | alternatfunc bit2=4 | alternatfunc bit1=3
* default | 1 | 0 | 0
* alt_A | 0 | 0 | 1
* alt_B | 0 | 0 | 0
* alt_C | 0 | 1 | 0
*
* ALTERNATE_FUNCTIONS(1, 0, UNUSED, UNUSED),
* means that pin AB9540_PIN_R4 (pin 1) supports 2 mux, so only GPIOSEL
* register is used to select the mux. As this pins doesn't support at
* least ALT_B mux, default mux is by writing 0 in GPIOSEL bit :
*
* | GPIOSEL bit=0 | alternatfunc bit2= | alternatfunc bit1=
* default | 0 | 0 | 0
* alt_A | 1 | 0 | 0
