Subject: [PATCH 5.13 153/175] usb: cdnsp: Fix the IMAN_IE_SET and IMAN_IE_CLEAR macro

From: Christophe JAILLET <christophe.jaillet@...adoo.fr>

commit 5df09c15bab98463203c83ecab88b9321466e626 upstream.

IMAN_IE is BIT(1), so these macro are respectively equivalent to BIT(1)
and 0, whatever the value of 'p'.

The purpose was to set and reset a single bit in 'p'.
Fix these macros to do that correctly.
