Commit 54ce6883 (davinci: da8xx: add spi
resources and registration routine) wrongly assumed that SPI1 is mapped at
the same address on DA830/OMAP-L137 and DA850/OMAP-L138; actually, the base
address was valid only for the latter SoC. Teach the code to pass the correct
SPI1 memory resource for both SoCs...

The MUSB driver doesn't see its platform device on DM644x EVM board anymore
since commit 73b089b0 (usb: musb: split davinci
to its own platform_driver) because the new probe is called as subsys_initcall()
now, and the device is registered later than that by the board code.  Move the
registration to davinci_evm_init() -- it's safe to do so because the MUSB core
device still gets initialized as fs_initcall() -- which is late enough for the
I2C GPIO expander (which controls VBUS) to be initialized.

For DMA operation, the davinci spi driver needs an event queue number.
Currently, this number is passed as a IORESOURCE_DMA.  This is not
correct, as the event queue is not a DMA channel.  Pass the event queue

This patch fix a bug in the register indexing for GPIOs numbers >  31
to get the relevant hardware registers of tnetv107x to control the GPIOs.

In the structure tnetv107x_gpio_regs:

struct tnetv107x_gpio_regs {
            u32     idver;
            u32     data_in[3];
            u32     data_out[3];
            u32     direction[3];
            u32     enable[3];
};

The GPIO hardware register addresses of tnetv107x are stored.
The chip implements 3 registers of each entity to serve 96 GPIOs,
each register provides a subset of 32 GPIOs.
The driver provides these macros: gpio_reg_set_bit, gpio_reg_get_bit
and gpio_reg_clear_bit.

The bug implied the use of macros to access the relevant hardware
register e.g. the driver code used the macro like this:
'gpio_reg_clear_bit(&reg->data_out, gpio)'

But it has to be used like this:
'gpio_reg_clear_bit(reg->data_out, gpio)'.

The different results are shown here:
- &reg->data_out + 1 (it will add the full array size of data_out i.e. 12 bytes)
- reg->data_out + 1 (it will increment only the size of data_out i.e. only 4 bytes)
