[PATCH v3 0/2] Fix deadlock during RSCI FIFO overrun error

[Biju]

From: Biju Das <biju.das.jz@xxxxxxxxxxxxxx>

This patch series aims to fix 2 issues
 1) Fix deadlock during RSCI FIFO overrun error, as wrong register used to
    clear the status.
 2) Hardware flow control is supported on all SoCs. Fix the binding.

v2->v3:
 * Added Rb tag from Geert for binding patch.
 * Dropped overrun_clr from struct sci_port_params_bits
 * All of the CFCLR_*C clearing bits match the corresponding
   CSR_*status bits. So, reused the overrun mask for irq clearing.
v1->v2:
 * Split the fixes patches from original series [1]
 * Updated commit message to make it clear that hardware flow control
   supported on all SoC for patch#1
 * Added Ack from Conor for patch#1
 * Added fixes tag for patch#1
