[i2c] Remove I2C IOCTLs

Removed add/rm slave and set frequency IOCTL functionality as we
expect to manage devices via board definitions and removed the calls
from the 'i2c' uapp. Also removed the slave irq IOCTLs which is now
unsued. Kept the transfer IOCTL for future app access to I2C
transactions.

ZX-2621 #comment Remove I2C IOCTLs.

Test: Boots on Pixelbook.

[dev][i2c][intel-i2c] Use I2C protocol instead of I2C get IRQ IOCTL

The Intel I2C driver supports IOCTLs that are used by other drivers,
this change replaces drivers calls to IOCTL_I2C_SLAVE_IRQ with
a new I2C protocol call i2c_get_interrupt(). This is a step
towards removing IOCTL based communication between drivers.

Test: 'hidtouch' in Acer12 (touch panel HID support gets an I2C IRQ)

[dev][i2c][intel-i2c] Use I2C protocol instead of I2C transfer IOCTL

The Intel I2C driver supports IOCTLs that are used by other drivers,
this change replaces drivers calls to IOCTL_I2C_SLAVE_TRANSFER with
the I2C protocol's calls i2c_transact() and friends. This is a step
towards removing IOCTL based communication between drivers.

[syscalls][ddk] Interrupt syscall improvements:

It is now possible to wait for multiple interrupts on a single interrupt handle.
The zx_interrupt_bind() syscall is used to bind an interrupt vector to
an interrupt handle, allowing up to 62 interrupt vectors per handle.

The zx_interrupt_get_timestamp() syscall can now be used to retrieve a
timestamp for an interrupt.

Virtual interrupts are now supported. zx_interrupt_bind() can be used to
designate an interrupt slot as a virtual interrupt, and the virtual interrupt
can be signaled using the zx_interrupt_signal() syscall.

The zx_interrupt_complete() syscall has been removed.
Instead, zx_interrupt_wait() now handles unmasking the interrupt
at the right time depending on whether the interrupt is edge or level triggered.

Slot ZX_INTERRUPT_SLOT_USER is reserved as a virtual interrupt, and is typically
used with zx_interrupt_signal() to unblock interrupt threads so they can exit
at driver shutdown or to perform periodic work.

Currently PCI interrupt handles can only be bound to a single interrupt vector,
but it is possible to bind virtual interrupts to PCI interrupt handles.

[ddk] Remove driver bind() cookie and unbind() callback

Also removed "owner" and "owner_cookie" from internal zx_device_t struct

Adjusted intel-hda audio drivers to create devices to hold driver context
rather than using the driver bind cookie.

[i2c-hid] For noirq devices, retry on read failure

On Acer12, which runs in noirq mode, the touchpanel driver instance
fails from a missing ACK of the address byte during this device_read.

The noirq mode doesn't follow the I2C-HID spec, and may be triggering
some undefined conditions by reading too early. If it encounters a read
failure, just try again.

[i2c-hid] Add workaround for lack of interrupts

It seems to be implementation-defined what reading from the
input register returns if you haven't received an interrupt yet.
Some devices we've seen return a 0 length report, and some return
the last seen report. This handles the last seen report case.
