arm: gic-v3-its: Fix LPI pending table size calculation
The variable `pend_tab_total_sz` is calculated using the macro
`LPI_PENDBASE_SZ`, which depends on the global variable `lpi_id_bits`.
However, `lpi_id_bits` is initialized later in the function based on
the GICD_TYPER register. This results in `pend_tab_total_sz` being
calculated with an uninitialized `lpi_id_bits` value (0), This leads
to the LPI pending tables being mapped with an incorrect size.
Fixes: 60b9b47d295b ("Revert "arch: arm: use dt and UCLASS_SYSCON to get gic lpi details"")
