reset: Add DesignWare IP support to simple reset
The reset-simple driver can be now used on DesignWare IPs by default by selecting the following compatible strings: - snps,dw-high-reset for active high resets inputs - snps,dw-low-reset for active low resets inputs Signed-off-by: Gustavo Pimentel <gustavo.pimentel@synopsys.com> Signed-off-by: Luis Oliveira <luis.oliveira@synopsys.com> Signed-off-by: Philipp Zabel <p.zabel@pengutronix.de>
