Refactor the `of_id_info` methods in the `Adapter` trait to reduce
duplication. Previously, the method had two versions selected
via `#[cfg(...)]` and `#[cfg(not(...))]`. This change merges them into a
single method by using `#[cfg]` blocks within the method body.

According to Bspec, bits 0~9 of MI_STORE_DATA_IMM must not exceed 0x3FE.
The macro MI_SDI_NUM_QW(x) evaluates to 2 * x + 1, which means the
condition 2 * x + 1 <= 0x3FE must be satisfied. Therefore, the maximum
valid value for x is 0x1FE, not 0x1FF.
v2
- Replace 0x1fe with macro MAX_PTE_PER_SDI (Auld, Matthew & Patelczyk, Maciej)
v3
- Change macro MAX_PTE_PER_SDI from 0x1fe to 0x1feU (De Marchi, Lucas)

When a PCIe device detects an error, it logs the error locally and issues
an error Message routed to the Root Complex (PCIe r6.0, sec 6.2.5). If the
Root Port or RCEC supports AER and Linux has enabled the AER interrupt,
aer_isr() traverses the relevant devices and adds those with AER errors
logged to the aer_err_info.dev[] array for error logging and recovery.
If aer_isr() finds more than AER_MAX_MULTI_ERR_DEVICES devices with AER
errors logged, it silently ignores them, and those extra devices are not
included in the recovery flow.
Emit an error message if we find more than AER_MAX_MULTI_ERR_DEVICES
devices with AER errors logged.

Currently swap is restricted before drivers have had a chance to do
their prepare() PM callbacks. Restricting swap this early means that if
a driver needs to evict some content from memory into sawp in it's
prepare callback, it won't be able to.
On AMD dGPUs this can lead to failed suspends under memory pressure
situations as all VRAM must be evicted to system memory or swap.
Move the swap restriction to right after all devices have had a chance
to do the prepare() callback. If there is any problem with the sequence,
restore swap in the appropriate dpm resume callbacks or error handling
paths.
