<id>cdd30ebb1b9f36159d66f088b61aee264e649d7a</id>
<content type='text'>
Clean up the existing export namespace code along the same lines of
commit 33def8498fdd ("treewide: Convert macro and uses of __section(foo)
to __section("foo")") and for the same reason, it is not desired for the
namespace argument to be a macro expansion itself.

<content type='text'>
The driver has intel_lpss_platform_info structs for I2C, SPI, and UART.
The I2C and UART structs are named with "i2c" and "uart" in the variable
name, whereas SPI ones do not mention "spi".

Rename the SPI related info structs to include "spi" in their names for
consistency and to make it obvious in the device ID list what kind of
device the line relates to.

Some devices (eg. Dell XPS 9530, 2023) due to a firmware bug have a
misconfigured clock divider, which should've been 1:1. This introduces
quirk which conditionally re-configures the clock divider to 1:1.

The pci_alloc_irq_vectors() returns a positive number on success.
Hence we have to filter the negative numbers for error condition.

With the help of EXPORT_NS_GPL_DEV_PM_OPS() and other *_PM_OPS() macros
we may convert PM ops functions to become static. This also takes into
account the PM configuration options such as CONFIG_PM and CONFIG_PM_SLEEP.
This all removes a lot of ugly macros and ifdeffery in the driver.
