irqchip/qcom-pdc: Tighten ioremap clamp to single DRV region size

The QCOM_PDC_SIZE constant (0x30000) was introduced to work around old
sm8150 DTs that described a too-small PDC register region, causing the
driver to silently expand the ioremap to cover three DRV regions. Now
that the preceding DT fixes have corrected all platforms to describe only
the APSS DRV region (0x10000), the oversized clamp is no longer needed.

Replace QCOM_PDC_SIZE with PDC_DRV_SIZE (0x10000) in the clamp so the
minimum mapped size matches a single DRV region. The clamp and warning
are intentionally kept to preserve backward compatibility with any old
DTs that may still describe a smaller region.

While at it, rename PDC_DRV_OFFSET to PDC_DRV_SIZE since the constant
represents the size of a DRV region and is used as both the ioremap
minimum size and the offset to the previous DRV region.
