Convert the driver to use regmap to access the chips. Due to the convoluted
register mapping scheme, implement read/write/volatile check functions that
untangle the mess and perform check accordingly. This patch does not zap the
internal register cache of the PCA953x driver, nor does it push the regmap
access down into the gpiochip accessors to simplify the review. All that is
in subsequent patches.

The multi-byte IO on various pca953x chips requires the auto-increment bit,
while other chips toggle the LSbit automatically. Note that LSbit toggling
only alternates between two registers during the IO, it is not the same as
address auto-increment. The driver currently assumes that #gpios > 16 implies
auto-increment, while #gpios <= 16 implies LSbit toggling. This is incorrect
at there are chips with 16 GPIOs which require the auto-increment bit.
The PCA9575, according to NXP datasheet rev. 4.2 from 16 April 2015, section
7.3 Command Register, the bit 7 in command register is the auto-increment
bit, which allows programming multiple registers sequentially.
Set this bit both in pca953x_gpio_set_multiple(), where it fixes the multi
register programming, and in pca957x_write_regs_16(), where is simplifies
the function. In fact, the pca957x_write_regs_16() now looks rather similar
to pca953x_write_regs_24() and pca953x_write_regs_16(), which is intended
for subsequent patches.

The PCAL_PINCTRL_MASK is too large. The extended register block on
PCAL6524, which is the largest chip with this block, has the block
limited to address range 0x40..0x7f. This is because the bit 7 in
the command register is used for the Address Increment functionality.
Trim the mask to 0x60 to match the datasheet and to prevent accidental
overwrite of the AI bit.
